An arrest has been made after a fourth groping incident in the False Creek area was reported to Vancouver police.

The Vancouver Police Department announced today (August 27) that after a series of sexual assaults against three girls took place on the False Creek seawall near Granville Island and Science World in the afternoon on August 17, a fourth person contacted police about an assault.

After police issued a call for public assistance in these cases, a 12-year-old girl reported to police that she had been groped and sexually assaulted at the Granville Island Public Market on August 13.

At a news conference, VPD spokesperson Sgt. Steve Addison explained that investigators were able to collect enough evidence from the fourth incident for an arrest and to have charges approved in that case. Meanwhile, investigators are still collecting evidence for the other cases.

Officers arrested 42-year-old Derek Sangris of Vancouver, who is charged with one count of sexual assault and one count of sexual interference in relation to the August 13 incident.

Police are continuing to investigate if this incident is connected with the other sexual assaults in the area.

In the August 17 incidents, two 11-year-old girls were groped by a male suspect on a bike near Granville Island. About half an hour later, a 15-year-old female jogger on the False Creek seawall was groped by a male suspect on a bike near Science World.

Anyone with information about these incidents is asked to call VPD Sex Crimes Unit at 604-717-0601.

The VPD has previously reported that there has been an increase in sexual assaults in the Granville Entertainment District, have been investigating several gropings in Champlain Heights, and arrested a male suspect who groped a man and physically assaulted a woman.
