Terry and Brendan McMillan were stabbed to death at a commercial building in Southwark, central London, on Monday
The two people who died in a quadruple stabbing have been named as a father and son.
‌
A man has been arrested on suspicion of murder after Terry McMillan and Brendan McMillan were fatally stabbed at a business premises in Long Lane, Southwark, London. The pair worked at the business in Studio One.
‌
An employee of Terry McMillan confirmed it was Terry and Brendan who were killed. Rosemary George, 59, has worked as a cleaner for the family for the last 14 years, both at their home in Chislehurst and at their business.
‌
Rosemary George, 59, told The Mirror: 'Terry and Brendan have passed away. I have worked with them for 14 years. I'm just on the way to the house now in Chislehurst. I watched Brendan finish secondary school. From secondary school he went to college and then university for four years.
'He had a gap year in America. He did physical education and was good at rugby as well. I WhatsApped him yesterday at 3pm and there was no answer. I was calling the office and there was no answer. I didn't know what had happened. I found out this morning.
‌
'I have cleaned their house for almost ten years - twice a week at the house and here once every three weeks. The office has roughly seven or eight people working there. It's not huge. Not all of them are family. I was worried because normally someone would always pick up the phone and nobody was picking up the phone."
Emergency services were called to Long Lane in Southwark at about 1pm on Monday after reports of multiple stabbings inside a commercial property, where they found and treated four people for stab wounds. A 58-year-old man was pronounced dead at the scene and three other men were taken to hospital, the Metropolitan Police said.
‌
A 27-year-old man later died in hospital, police said. On Tuesday, police said a 31-year-old man, who is a British citizen and was initially detained in connection with the incident, was arrested on Monday. He remains in hospital and his condition is not life-threatening, they added.
Witnesses said they saw a man pinned down in an alleyway outside the offices of Trademark Group, the McMillan family's firm which is involved in projects across Bermondsey.
A man who works inside the building said: 'I saw him get tackled to the ground. There were 12 to 15 people out the back. There was a load of commotion, hundreds of people looking out from the balconies. He was on the ground, facing down, shirtless.'
Another worker said a 'fight' between men went into the lobby of the Marriott Hotel next door. She said: 'It went into the hotel and back out, so it was closed off yesterday and people in hazmat suits went in."
A nearby resident who knows Brendan said they had seen a video of a man they thought was him being wheeled to an ambulance after the incident. The woman said she had not heard it was him who had died. But she said she feared the worst after seeing the video and that his car had not moved from outside the business in the 24 hours since it happened.
