British police on Monday said a man had been arrested on suspicion of murder after   3 women and a man have been discovered dead at a property in south London.

Officers pressured access to a residential address in Bermondsey, inside the Southwark region of the capital, after reviews of a disturbance at approximately 1:40 am (0040 GMT).

“Inside the house, they made a dreadful discovery of four people who had been stabbed,” Colin Wingrove, a police detective, told reporters.

“Despite the efforts of officers and paramedics, all four people were sadly pronounced dead at the scene.”

Wingrove said the three women were believed to be in their 30s, 40s, and mid-60s, while the male victim was also thought to be in his mid-60s. The man arrested was in his late 20s.

“At this early stage, we are not currently looking for anyone else in connection with this incident,” he added.

“We believe that all those involved may have been known to each other.”

Post-mortem examinations may be performed to decide the exact purpose of death. The guy arrested changed into taken into custody at a south London police station.
