The enhanced police presence for the race will remain in place despite the death and capture of the Boston Marathon bombing suspects, Scotland Yard has said.

Security has been stepped up to reassure the 36,000 runners and tens of thousands of spectators in the wake of the atrocities which killed three people and injured 180 in the US last Monday (April 15).

After a manhunt which left Boston in virtual lockdown, 19-year-old Dzhokhar Tsarnaev was arrested following a shoot-out with officers and his brother Tamerlan, 26, was killed yesterday (April 19).

But several hundred more officers will still be out on London's streets tomorrow - a 40 per cent increase on last year.

The race's chief executive insisted the bloody events in Massachusetts will not put off spectators or runners taking part in the 26.2-mile event.

Nick Bitel said the boosted police presence would help ensure the event will be "as safe and fun as it always is".
