Teenagers from Orpington and Sidcup have been arrested on suspicion of supplying drugs after a 15-year-old died of an overdose on Saturday.

Tributes to Emre Huseyin have poured in since he collapsed suddenly and died at his Kent home on Saturday, five days before his sixteenth birthday.

It is believed that Emre, who lost his mother at the age of three, had been experimenting with drugs alongside a friend.

Another teenager, who has not been named, was taken to hospital on Saturday and later discharged.

Police arrested a teenager from Orpington on suspicion of supplying drugs on Saturday. He was bailed, pending further enquiries.

A second teenage boy, from Sidcup, was arrested on Monday and was still being interviewed yesterday.

Last year Emre was invited to Wembley Arena to be commended by Prince Harry and Meghan Markle for the work that he and his classmates had done at their school's dementia cafe.

The initiative supports older people suffering from the disease, and was supported by the Queen's Commonwealth Trust, of which Harry is president.

While he didn't meet the Sussexes face-to-face, one of Emre's classmates presented a then-pregnant Meghan with a teddy bear for baby Archie backstage at the invitation-only concert.

Emre's eldest sister Ceren Huseyin, 20, said: "He was a smart boy and getting on so well at school. He was friendly, and loved going out with his friends.

"He will be sorely missed. We all loved him so very much. It is such a terrible loss.

"This was so unexpected. He had many plans. He was full of aspirations.

"He wanted to study psychology and business in the sixth form. He had such a big future ahead of him. He loved reading and drama and was in school plays."

The family moved to Sheppey from Lewisham five years ago, in pursuit of a fresh start.

Ceren said: "We wanted to live somewhere where there wasn't so much crime."

Emre quickly settled into his studies at the Oasis Academy, and soon became a fixture at the school's award-winning cafe.

Days after his death, floral tributes were still propped against the wall of Emre's home in Sheerness - where he lived with his father, sisters Ceren and Seren, 17, step-mother and two-year-old step-brother.

He has two older brothers who live in Cyprus and Poland.

His father, Yusuf Sakaryali, had been visiting another son in Cyprus when he was told the devastating news and flew back on Sunday.

At evenings and weekends Emre would work at a local barber's shop to earn some pocket money.

The shop's owner, Nicolae Costin-Christian, said: "He was a very good boy. He would open the door for customers, show them to a seat, offer to get them a coffee and then sweep up their hair from the floor afterwards.

"I first met him when he came into the shop to have a haircut with his father. I have watched him grow up.

"I understand Emre might have taken something but if he did then it was very out of character. I have never seen him touch a cigarette or drink alcohol."
