Knife crime: Mum tells teenagers about her son’s murder

Jean Foster’s son Christopher was murdered in a case of mistaken identity in 2013 while out with friends in Borough High Street.

She’s been telling her story to teenagers at a school in east London to try to deter them from carrying a knife and getting involved with violent gangs.

The presentation was part of a campaign by the Metropolitan Police to try to curb a potential rise in violent crime as lockdown restrictions ease ahead of the school summer holidays.
