A police hunt is on to find a man after a “true gentleman” bus driver was killed in a brutal stabbing.

The Metropolitan Police is hoping to speak to Kamar Williams, 33, who lives in the Isle of Dogs but is also known to frequent both east and south east London.

Members of the public have been warned they should not approach him, and instead should alert police immediately.

It follows after the murder of Derek Thomas, 53, who was killed in a Northwold Road, Stoke Newington, on Tuesday (July 30) at 11.05pm.

The Stoke Newington local was reportedly attacked on his way back home after work at the Northumberland Park bus garage in Tottenham for transport company Go-Ahead London.

A post mortem examination held at Poplar Mortuary on Thursday (August 1) gave the cause of death as a stab wound to the chest.

His next of kin are aware and are being supported by specially trained officers.
