The fourth suspect allegedly involved in a robbery of a cannabis store last month has been arrested.

On October 16, a group of four people armed with guns entered the Stressed and Depressed cannabis shop at 1353 East 41^st Avenue. They robbed the business of cash and products and assaulted one staff member.

While police arrested three men on October 22 in Surrey and Delta and charged them with a range of robbery- and weapons-related offences, they were unable to find the fourth person, 23-year-old Brittany Ulmer-Wightman. A warrant was issued for her arrest.

On November 3, the Vancouver Police Department appealed to the public for assistance in locating her.

She was arrested on November 6 in Surrey by RCMP.

She was charged with robbery, use of an imitation firearm in commission of offence, and sexual assault.

She will remain in jail in Vancouver until her next court appearance.
