Detectives from Trident are appealing for witnesses and information following the murder in Clapham Road, near to Stockwell underground station.
Police officers patrolling in the area heard shots fired in Clapham Road, SW8 near to the underground station at 23:30hrs on Tuesday 31 May. A 25-year-old man received gun shot wounds and was taken to a south London hospital. He was pronounced dead at 00:29hrs.
He has been formally identified as Sadiq Adebiyi, 25, from the Stockwell area. Next of kin has been informed. A post-mortem will take place in due course.
At this early stage it is believed the victim was standing in Clapham Road on the pavement directly outside Richardson Court when he was shot. A dark coloured motorcycle carrying two men wearing dark clothing and helmets crossed Clapham Road from the direction of the Stockwell Gardens Estate. Following the shooting the motorcycle left the scene at speed and was pursued by a marked police van, which was passing at the time, into Binfield Road.
Officers arrested a 19-year-old man in Battersea a short time later. A 21-year-old man was arrested in Battersea on Wednesday 1 June. They remain in custody at south London police stations.
Detective Chief Inspector Neil Hutchison, Trident, said:
"I am appealing to anyone who may have witnessed this incident to come forward and speak to the police. I am particularly keen to hear from anyone who may have seen the motorcycle travelling at high speed towards the Battersea area. The police van pursued the motorcycle into the Patmore Estate. I believe there were two suspects on the motorcycle at the time and that one of the suspects got off somewhere in the estate. When police stopped the motorcycle they arrested the 19-year-old rider. I would like to hear from anyone who saw a person getting off a motorcycle in the Patmore Estate shortly before midnight on 31 May."
Trident would also like to stress that witnesses who are fearful can be protected and provided with anonymity in a court case. Trident has extensive experience in witness protection and anonymity and has used it successfully on many occasions.
Detectives are asking anyone with information to call the incident room on 020 8247 4553 or to remain anonymous, call Crimestoppers on 0800 555 111.
