Winnipeg police laid another charge against alleged serial killer Shawn Lamb on Tuesday.
Lamb was in court Tuesday morning to face a charge of sexual assault stemming from an incident between November and December 2011.
Police said a woman met with a man near Jarvis Avenue and Powers Street and was then driven to a secluded area and seriously sexually assaulted with a weapon.
She was able to flee to a nearby business and notify police.
Court documents state the weapon used was an anti-theft steering wheel lock.
Now, Lamb faces one charge of sexual assault with a weapon in addition to three charges of second-degree murder.
He is scheduled to appear in a Winnipeg courtroom again on Thursday.
