A group of four woman who saw the single blow which killed banker Oliver Dearlove have come forward to speak to police.

The 30-year-old died in hospital after being assaulted in Tranquil Vale on Sunday, August 28, while out with friends from university.

Police and paramedics were called and he was airlifted to hospital but died less than 24 hours later. A post-mortem examination held at Greenwich Mortuary on Monday, August 29, gave the provisional cause of death as intracranial haemorrhage. Further tests are ongoing.

Detectives investigating his murder have tracked down the woman who were speaking to Oliver and his friends at the time of the fatal attack. The victim and his friends were waiting for a pre-booked taxi following a night out in a Montpelier Vale bar.

They said a man approached the group and struck Oliver causing him to collapse. He then left, possibly in the direction of the Heath.

Detective Chief Inspector Lee Watling, who is leading the investigation, said they were now trying to track down CCTV of the suspect and added: “In the meantime, I would encourage the man to come forward and speak to me about the events of Sunday night.”

He thanked those who had come forward but appealed for anyone else who saw the Blackheath Village attack to get in touch.

“Oliver’s family, his girlfriend and friends have been left devastated by his death and deserve to know what happened to him. If you have any information, no matter how insignificant you think it is, contact the police.”

Anyone with information should call the police incident room on 0208 721 4205 or Crimestoppers anonymously on 0800 555 111.
