Alleged child sex offender Abraham Kiewiet has been charged with 10 additional counts related to five victims, Vancouver police announced Friday.

Police said the alleged assaults on male and female victims between the ages of 12 and 16 took place between 1975 and 1982 when the accused worked as a lifeguard for the Vancouver Park Board.

Kiewiet, 70, is now charged with a total of 22 offences involving 10 victims. Eight counts of indecent assault on a male, three counts of indecent assault on a female and 11 counts of gross indecency have been laid.

“These victims came to us after learning of this investigation following a public appeal for information in September of this year,” says Sgt. Matt Clarke of the Vancouver Police Sex Crimes Unit.

“These men and women should be admired for their courage in coming forward after living with these memories of sexual abuse for the past 25 years.”

Investigators believe there are additional victims, both locally and outside B.C., who have not yet come forward.

Anyone with information is asked to call Vancouver police at 604-717-0618.
