One of the teenage suspects in the shooting of five-year-old Thusha Kamaleswaran has been stabbed.

The 17-year-old is in a “serious but stable” condition under police guard in hospital, sources confirmed.

He was admitted to hospital with stab wounds on Saturday - a day before his arrest on suspicion of the attempted murder of Thusha and 35-year-old Roshan Selvakumar.

Thusha, from Hainault in east London, was hit in the chest and Mr Selvakumar suffered a head wound as two youths cowered in the Stockwell Food and Wine store after being chased by three others on bicycles through Stockwell.

Her mother, 12-year-old brother and three-year-old sister were also in the shop during the shooting but were unhurt.

The stabbed teenager is one of four suspects arrested in connection with the double shooting.

Kazeem Kolawoli, aged 18, of Black Prince Road, Lambeth, and Anthony McCalla, aged 19, of Oakdale Road, Streatham, have both been charged with two counts of attempted murder.

After appearing at Camberwell Green Magistrates’ Court they were remanded in custody for a hearing at the Old Bailey on June 10.

The 17-year-old boy who was stabbed remains in custody, while a 14-year-old has been bailed to a later date.

The youth is understood to be recovering at King’s College Hospital, where medical staff are caring for Thusha following surgery.

The stabbing is believed to be unrelated to the shooting.

Police are returning to the scene of the shooting tonight to hand out leaflets and seek witnesses exactly one week after the incident.

Detective Chief Inspector Tony Boughton said: “We have had a fantastic response from the local community, who are working with us on this investigation.

“Tonight between 8pm and 10pm Trident detectives, assisted by the local borough police, will be out on the streets of Stockwell encouraging witnesses to come forward with information.

“There are still some witnesses that we haven’t spoken to and we would like to hear from anyone who may have seen the incident or have information that may assist us.”

Scotland Yard said Mr Selvakumar has been discharged from hospital but continues to receive treatment for his injuries.
