One of the world's most wanted men, Hillingdon-born Roy Lawrence Piechocki is still at large according to Interpol.
Now aged 56, he is wanted for 10 counts of sexual exploitation against a minor in the United States.
Piechocki is subject to a red notice from Interpol, an intergovernmental organisation working to facilitate international police cooperation.
A red notice means Interpol is looking to find the man and arrest him "with a view to extradition or similar lawful action".
He is described as just under 6ft tall with blue eyes and brown hair, and a global police hunt is being carried out to find him.
Piechocki was born in Hillingdon in 1961 and has been a fugitive for several years.
If you have seen this man or think you might know where he is, please contact Metropolitan Police or your local police force with the information.
