A teenage university student who died after he was gunned down in an apparently random attack was described as a young man whose "smile will charm the angels".

Joseph Burke-Monerville, 19, was in a parked car when he was shot in Hindrey Road, Clapton, east London, on Saturday evening. Mr Burke-Monerville, who according to his Facebook page was studying forensic science at the London Metropolitan University, had no links to gangs, Scotland Yard believe.

He was rushed to hospital but died later. A 22-year-old man who was also in the car remains in a serious but stable condition, while a third man, aged 19, was also in the vehicle but escaped unhurt, police said.

Mr Burke-Monerville had spoken on Facebook of his excitement about a planned holiday to Magaluf on the Spanish island of Majorca next week, which he said would be "a week 'off' stress".

He wrote that he had previously attended Aloysius' Roman Catholic College, in Highgate, north London and Wesley High School, in Otukpo, Nassarawa, Nigeria.

Mr Burke-Monerville, from the Islington area, died at about 11.10pm, police said. A post-mortem examination is due to take place on Monday.

Police said there was as yet no clear motive for the shootings, and no-one has been arrested.

Detectives from Operation Trident, which investigates gang-related crime, are hunting the two suspects seen running from the scene. One is black, police said, while the second is light-skinned, possibly of Asian or Turkish appearance. They were seen running away from Hindrey Road after the shooting towards the nearby Pembury Estate.

Det Chief Insp Kenny McDonald, who is leading the inquiry, said: "Our early inquiries suggest that Joseph and those he was in the car with have no links to gangs. We continue to work to try and establish the motive for this murder. I would urge anyone who was in the area at the time of the shooting and may have seen the incident, or two males fleeing the scene, to contact officers." Witnesses to the shooting or anyone with information about the incident are asked to call police on 101 or Crimestoppers on 0800 555 111.

A post-mortem examination, which took place on Sunday at Poplar Mortuary in east London, gave cause of death as a gunshot wound to the head, Scotland Yard said.
