Six people in B.C. including four youths have been arrested in connection with what RCMP are calling a "horrific sexual assault" on a young male who police believe was lured to a Prince George apartment earlier this week.

Police say the investigation began on Monday when they were tipped off that a male was lying in a snow bank behind an apartment building on the 1600 block of Juniper Street.

The unconscious youth was taken to hospital where it was determined he had been physically and sexually assaulted. Police then also learned that a second youth had also been assaulted, according to Cpl Craig Douglass.

"Police have determined that the victims were targeted and lured to the apartment building where they were assaulted by a group consisting of both youths and young adults," alleged Douglass.

Over the next two days investigators from the serious crime unit executed five search warrants and arrested six people including:

An 18-year-old male.

A 20-year-old female.

Three male youths.

One female youth.

One victim remains in hospital in serious but stable condition.

"I haven't come across in my career, and I have had officers with more than 20 years experience tell me the same thing, in regards to the fact that youth and young adults can carry out such disturbing acts," said Douglass.

"This is a very disturbing investigation. We will do everything we can to bring those responsible to justice," said Douglass.

Police are asking anyone with information to contact the Prince George RCMP at 250-561-3300 or anonymously contact Crime Stoppers at 1-800-222-8477.
