CCTV images of suspects in the Michael Jonas murder investigation have been released by police.

This follows the announcement of a £20,000 reward for information leading to the identification, arrest and prosecution of the person or people responsible.

Police were called shortly before 7.30pm on Thursday, November 2, 2017, to Betts Park in Penge, and arrived to find Michael with multiple stab wounds.

He died at the scene just after 8.15pm, with a post-mortem exam the next day confirming he died of stab wounds to the chest and haemorrhage.

On Monday, January 15, the Crown Prosecution Service and the Met discontinued murder charges against six people, but are releasing fresh images of five male suspects on bikes.

Suspect one is described as a black male, riding a BMX style bike with a silver frame and red writing.

The second suspect is described as black and riding a bike with silver coloured handles.

The third suspect is described as black and riding a black framed bike with a brown saddle and reflector on the wheels.

Suspect four is described as white and riding a mountain style bike with a rear mud guard and thick black tyres.

Suspect five is described as a light skinned black male with a plait hairstyle and riding a black framed bike with silver mud guards. The rear wheel is also described as having a metal frame and a flashing red light at the back.

DCI Richard Leonard said: "Just twenty minutes before Michael's murder, they were seen on CCTV travelling from McDonalds in Penge to Annerley Way; the road just outside the park where Michael died a short while later.

"The suspects also match the description provided by individuals who witnessed Michael being chased in the park.

"He was found by officers lying in complete darkness but in a busy park so I'm confident someone out there knows what happened that evening and has vital information that could help us identify those involved in Michael's death.

"I would like to reassure the public that any information, no matter how small, will be treated in the strictest confidence.

"Michael was a young man whose life was brutally taken too soon. If you have any information, I urge you to get in touch and help us get justice for Michael."
