Abraham Badru's mother: Dalston killing 'was revenge'

Abraham Badru was shot in the chest in Dalston, east London, on 25 March while speaking on the phone with a friend.

The 26-year-old received a bravery award in 2009 after he saved a girl from being gang-raped at a party, later giving evidence against her attackers.

His mother Ronke said she believed "in my heart" it was why he was killed.
