Two arrests on suspicion of rape were made after police used new technology in Catford and Lewisham.

The arrests were made on Tuesday, March 26, along with one arrest for breaching a sexual harm prevention order, one for breaching home detention curfew and one on suspicion of drug offences.

Police used live facial recognition to compare the images of people passing by with a watchlist of people police want to speak to.

When a match is made, an alert is sent to police which they will review and decide if they want to speak to the individual.

A spokesperson for the Metropolitan Police said: “As part of our ongoing commitment to listen to our communities and tackle crime in their areas, we deployed our Live Facial Recognition (LFR) technology on the streets of Lewisham and Catford yesterday, Tuesday, 26 March.

“There were five arrests during this operation - two for rape, one for breaching a Sexual Harm Prevention Order, one for breach of home detention curfew and one for drugs offences.

“LFR is a precision technology that allows images of a person passing the deployment to be compared against a bespoke watchlist of people who the police wish to speak to.

“When a match is made an alert is generated.

“An officer will review the match and decide if they wish to speak to the individual.”

The Met claims the technology helps officers to fight crime by identifying criminals. But privacy campaigners have branded the cameras ‘intrusive’ and ineffective compared to other policing methods.

In Lewisham town centre, a van with the technology was parked on the high street with approximately eight officers stationed in pairs around it.

Some members of the public paused to read signs put up by police near the vehicle explaining the cameras. Others asked officers what was happening. 

One passerby, Lewisham resident Loveday Cole, seemed unsure what to make of the cameras. He said: “It’s a bit weird. Fair enough they’re using it to catch criminals and we don’t want criminals on the street but it looks a bit weird. When people get used to it, it’s not too much of a problem.

“If you’re not a criminal, you don’t have to worry about it. It’s only if you’re a criminal, you would be thinking oh my gosh. Some people are going to feel like it’s invading their human rights too.”

But Lau Ciocan, who also lives in Lewisham, said he was concerned about the technology being biased and the security of data held by the cameras.

The 41-year-old said: “You have to make sure that this technology is not biased. If you have a biased pool, it cannot recognise Black people’s faces and it might misidentify.

"How can we ensure that bias does not get propagated? How do we ensure the security of it so it’s not hacked?”

Mr Ciocan also made reference to an incident at Notting Hill Carnival in 2017 where a false match resulted in an incorrect arrest.

He added: “Do they run tests [of facial recognition cameras] in other boroughs that are [more] white? Do they do it in non-Black boroughs? What about places like Chelsea or Richmond? That’s my concern.” 

According to the 2021 census, 26.8 per cent of people in Lewisham said they were Black, Black British, Black Welsh, Caribbean or African compared to 7.9 per cent of people in Kensington and Chelsea and 1.9 per cent of people in Richmond upon Thames. 

The Met has previously used facial recognition cameras in Croydon and Tooting in Wandsworth. Last week the force made 17 arrests following the deployment of the technology in South London. 

Liam Shrivastava, chair of Lewisham Council’s safer stronger communities committee, which makes recommendations about police, crime and equalities, said the deployment of cameras was ‘deeply concerning’.

Writing on X, Councillor Shrivastava said: “[Live facial recognition] has serious racial bias and privacy implications, is legally dubious and has never been debated in parliament. Local consultation has been minimal, with elected members notified just two weeks ago.”

Madeleine Stone from Big Brother Watch said: “Everyone wants dangerous criminals off the street, but papering over the cracks of a creaking policing system with intrusive and Orwellian surveillance technology is not the solution.

“Rather than actively pursuing people who pose a risk to the public, police officers are relying on chance and hoping that wanted people happen to walk in front of a police camera.”

Lewisham Council said it was ‘carefully monitoring’ the use of facial recognition cameras and was in conversation with the Met and other local councils where the technology is being rolled out. 

Lindsey Chiswick, who is responsible for the technology at the Met said: “Live facial recognition is a precise crime fighting tool which helps officers identify criminals as part of proactive intelligence led operations tackling crime across London. 

“Where there is no match, all images are immediately and automatically destroyed. We understand the need to ensure sufficient safeguards are in place on our use of the technology and work closely with the London Policing Ethics Panel, set up by the mayor of London, to ensure this is the case.”
