Knife crime: Mums relive their hardest calls after sons were stabbed

Five mothers have relived the 'hardest' phone calls they each had to make after their sons were stabbed to death - in a bid to urge Londoners to speak up about knife crime.

They have shared their stories as part of a Hard Calls Save Lives campaign, which has been launched by the Met Police.

Met commissioner Dame Cressida Dick hopes their "tragic accounts" will encourage people to call the Crimestoppers charity anonymously.
