Half-eaten chocolate bar leads to jail for Birmingham robber
A robber who held a teenager hostage has been jailed for eight years after police found his DNA on a half-eaten chocolate bar his victim kept.
Mohammed Islam, 18, of no fixed address, lured the boy to a property in Brookpiece House, in the Druids Heath area of Birmingham, in March.
He threatened to kill him if his family did not send money to a bank account.
Islam pleaded guilty to robbery, false imprisonment of the 18-year-old and blackmail at Birmingham Crown Court.
West Midlands Police said during the three-hour ordeal, Islam started eating a Wispa chocolate bar while making demands for money from his victim's father.
The teenager managed to get hold of the chocolate bar and handed it to police when he was released which they said was "crucial" to securing a conviction.
Islam was arrested on 3 April, and was recaptured after attempting to escape from hospital where he was being treated for a police dog bite.
Det Con Darran Ford said: "This was a callous, planned attack that had great impact on the victim and his family, who I hope have now been offered some closure."
The victim's father said: "I hope that no father ever has to go through what I went through."
