A sexual predator who indecently assaulted 17 intoxicated young men in his car after picking them up from Perth nightspots has been jailed for three years and nine months.

Brendon Quintin Webb, 41, was sentenced in Perth Magistrate’s Court after pleading guilty last month to 17 separate indecent assaults dating back to 2017 — many on unidentified victims.

The horrifying abuse came to light earlier this year, after a 19-year-old man told police he woke up being abused in a stranger’s car in Doubleview in January.

The teenager told police it was several hours after he left The Avenue at Club Bayview at 1am when he woke, with his attacker telling him he was just trying to get him home.

Webb was arrested after police tracked the teenage victim’s GPS location from his phone on that night. Detectives then uncovered up to 20 videos, and several photos of other alleged victims, all believed to be men in their late teens to early 30s, in a search of Webb’s phone.

Only four of the victims were identified on the prosecution indictment, with the rest catalogued as unidentified adult males.

The attacks occurred in January and February this year, November, October, May, March and January last year, and September, August and July 2017.

In sentencing Webb, Magistrate Richard Bayly said his offending was of a “serious” and “sinister” nature but accepted it was partly as a result of him trying to conceal his own sexual orientation.

Webb’s sentence was backdated to February 29 when he was taken into custody.

He was made eligible for parole after serving half of the term.
