Anti knife and gun crime campaigners have been holding a peace march in Edmonton.
It's thought up to 1000 people took part in the event, which started at Pymmes Park in Edmonton.
It took about an hour for campaigners to march to the nearby Art Zone, where seminars and workshops took place to teach young people about the dangers of getting involved with knives and guns.
The march was set up by a mum of seven, who's told London's Heart she decided to organise it after a 15 year old boy was stabbed to death in the area back in April.
