The Met Police said they needed to Taser the suspect to detain him and that he was in a stable condition in hospital.

The murder suspect arrested over the sick massacre of four family members in South Bermondsey is in hospital, after being Tasered by police officers during his arrest.

Detectives broke down the door of the home in Delaford Road at 1.40am on Monday, to make a “dreadful discovery” - finding three women and a man with stab wounds.

Dolet Hill, 64, partner Denton Burke, 58, daughter Tanysha Ofori-Akuffo, 45, and granddaughter Samantha Drummonds, 27, all tragically died at the scene.

Officers found a 28-year-old man in the house as well, and were forced to Taser him to arrest him on suspicion of murder.

Scotland Yard said the suspect, from Lewisham, remains in hospital where he is a stable condition. He remains under arrest.

Former NHS worker Ms Hill lived with Mr Denton in Delaford Road, South Bermondsey, while Ms Ofori-Akuffo lived in Kennington and Ms Drummonds lived in Forest Hill, Lewisham.

Southwark Borough Commander Ch Supt Colin Wingrove confirmed that detectives were not looking for any one else in relation to the deaths at this stage.

Special post-mortem examinations have been arranged for Tuesday and Wednesday after which formal identification is due to take place.

Police have urged any witnesses to come forward with information.

Det Ch Insp Linda Bradley, who leads the investigation, said: “This was a truly horrific incident and I fully recognise that the distress for the family and the community will be overwhelming.

“We are conducting a thorough and detailed investigation into the facts and we are appealing to anyone who can assist with any information to come forward.

“If you know anything or saw anything that you think might help us piece together the events which led to this, then do not hesitate, please call the police.

“You can also call Crimestoppers if you do not want to give your name.”

“We deeply appreciate all the help we have already received from local people and I would like to thank them for their patience and support in what is likely to be a protracted inquiry.

“We are moving as fast as we can at the scene, but we need to ensure we uncover all the facts and secure every bit of necessary evidence and this may understandably take some time.

“We are aware that we have family, friends and a community that are all asking questions, we are determined to give them the answers they deserve as soon as possible.”
