A man from south east London who stabbed his ex-girlfriend's new partner to death on a bus has been jailed. 

Oscar Castano-Colque, 21, of Woodfarrs in East Dulwich, repeatedly stabbed Rafioullah Malik on-board a bus in Oxford Circus on February 28 last year. 

In the days before the murder Castano-Colque had bombarded his ex-girlfriend with messages declaring his love for her and telling her their relationship wasn’t over. 

Rafioullah was taken to hospital where he later died almost a month later on March 23.

Detective Chief Inspector Wayne Jolley who led the investigation said: “Castano-Colque could not accept his relationship was over and his former girlfriend had moved on. 

“On the day of the attack we tracked his movements on CCTV to target the bus Rafioullah Malik was on in order to carry out his vicious and determined attack. 
“After stabbing Rafioullah numerous times, Castano-Colque left the bus and attempted to throw away his coat and the murder weapon.”

Police discovered the bloodstained clothing worn and the knife with the victim’s DNA. 

DC Jolley said: “This coupled with CCTV from on board the bus which captured the entirety of this crime, meant Castano-Colque had no choice but to plead guilty.” 

He was arrested a few days later and then pleaded guilty to murder. 

At Croydon Crown Court on Thursday (February 22) Castano-Colque was sentenced to life with a minimum of 25 years and six months.
