A former Burger King employee accused of repeatedly stabbing a waiter in an alley has blamed his sister’s boyfriend for the explosion of violence. Giving evidence at Canterbury Crown Court Lewis Day described how Daryl Brown threw a beer can at Modasher Hossain from a platform at Whitstable train station and then chased the 55-year-old into a nearby alleyway. Day, 25, said he had tried to stop Brown and, when he reached the alleyway himself, watched as the 32-year-old punched Mr Hossain unconscious with one blow, before knifing him several times and then walking off “like nothing had happened”…
