A Winnipeg doctor accused of sexual assault is back in police custody after being arrested in Greece.

Winnipeg police said Saturday that Walid Ahmed Abdelhamid, 30, was taken into custody Aug. 6 while travelling through an airport in Crete.

He had been the subject of a police warrant since August of 2009, when he failed to attend court in Winnipeg on the sexual assault charge.

The charge was laid in June of 2009. A publication ban has been in place since then relating to the details of the alleged assault because of the age of the victim.

Police have only reported that the victim, a male, was a patient at the Children's Hospital in Winnipeg and, at the time of the alleged assault, was between 13 and 17 years old.

After the charge was laid, Abdelhamid was released on bail and ordered to surrender his passport.

Abdelhamid, who is originally from Libya, was a postgraduate medical resident at the University of Manitoba.

Winnipeg police spokesman Const. Jason Michalyshen said Saturday that extradition could take weeks or even months.
