Bibaa Henry, 46, and Nicole Smallman, 27, were found stabbed to death in Fryent Country Park on June 7.

An 18-year-old was arrested overnight (July 1) at an address in south London on suspicion of both murders, said Scotland Yard.

He was taken into custody where he remains.

Det Chf Insp Simon Harding said: “This investigation into the awful death of two sisters is of course a priority for the MPS and my officers have been working around the clock to identify the person responsible.

“Given the significance of this development, we visited the family in person today to inform them of the arrest.

“ Our thoughts remain with them at this very difficult time.

“A team of forensic officers have been a constant presence at the park over the last few weeks carrying out meticulous fingertip searches at what is a vast and complex crime scene.

“Whilst that work has now concluded, smaller searches in outer areas of the park will continue.”

He added: “To date officers have recovered more than 1,000 exhibits – including property belonging to both Nicole and Bibaa, collected hours of CCTV and visited hundreds of homes and businesses. And those enquiries remain ongoing.”

Mum-of-one Bibaa, who lived in Brent and Nicole, who lived in Harrow, were stabbed to death in the early hours of June 6 in the park, off Slough Lane.

They were with a group of people who congregated in the park from around 7.40pm on June 5 to celebrate Bibaa’s birthday and by 12.30 am only the two sisters remained.

Both Nicole and Bibaa were reported as missing to police late on Saturday, June 6, when they did not return home and were discovered the following day.

Two Met police officers have also been arrested on suspicion of misconduct in a public office after allegedly taking selfies of the sisters after their bodies were found and sharing them to a social media group.

They are currently being investigated by the Independent Office for Police Conduct (IOPC).
