Two thugs wanted for extradition to Poland for brutal attacks where their victims suffered broken bones and damaged internal organs are thought to be hiding in Croydon.

The men are among 17 people hunted by the Metropolitan Police’s extradition unit as part of Operation Sunfire 4 for return to their home countries.

Dangerous Polish rapist 'may be hiding in Richmond'. Have you seen him?

Officers are appealing for Croydon Guardian readers to help track down Krzysztof Malkowski and Michal Ochecki.

Malkowski is wanted to serve a 19 month prison sentence in Poland for GBH after an attack on September 1, 2012.

He and another person lured their victim into a flat in Bydgoszcz, Poland, where they brutally kicked and punched him.

They broke his ribs and nose, damaged his lungs, kidney and spleen, and fractured his eye socket.

Police believe he may be in Croydon or Lambeth.

Ochecki has two years, five months and 28 days to serve in prison for a number of assaults in his home country.

On April 2, 2004, Ochecki - then aged 19 - and another suspect stole a calculator from a man in Sieradz, then punched him in the back of the head.

Four days later, they assaulted another person in order to steal their mobile phone.

On June 24, 2007, he and another suspect carried out an unprovoked attack on another man, in the same city.

They punched and kicked the victim in the face, breaking his nose and smashing his front teeth.

Ochecki, who also goes by the name Tomasz Baniak, is possibly in Croydon or Lambeth.

Detective Sergeant Peter Rance, who is leading the operation, said: ion Unit, leading Operation Sunfire 4, said: "We believe that these people are dangerous, so taking them out of our communities and putting them before the courts is of paramount importance.

"I urge the public to look closely at these pictures. Do you recognise these men? It may be that they live next door to you, or you see them regularly elsewhere in your community."

"If you have information on their whereabouts, please tell Crimestoppers, so that we can arrest them. If you see them, call 999 and do not approach them."
