A teenager from Edmonton has been arrested after a store was robbed in a Maple Ridge mall using, what witnesses described, as bear spray.

Police were called to ValleyFair Mall, along Lougheed Highway, between 227 and 228 Streets, at around 5:30 p.m. after receiving multiple calls about a robbery in progress.

According to witness statements to police, two men went into a store and attempted to break a display cabinet with a hammer.

鈥淎t one point during the incident a noxious substance, described by witnesses as 鈥榖ear spray鈥� was deployed by the suspects,鈥� said Sgt. Scott Grimmer with the Ridge Meadows detachment.

Although initial reports indicated that two men entered the business while two other men waited outside, Grimmer said that police are still trying to determine the actual number of suspects.

Off-duty security guard, Anne Frankel, who stopped at the mall to use the restroom, ended up being sprayed during the incident.

She said she saw two men standing facing an empty storefront 鈥� something that caught her eye as a security guard 鈥� as she chatted with a friend by a lottery store who was working security at the mall.

All of a sudden she heard glass breaking and a woman screaming. When her friend went running towards the commotion, she followed, calling 911, she said.

Frankel said one person was grabbed by her friend who put him in a headlock, but the other two boys 鈥渂ooked鈥�. And another, she said, came out of the store and began spraying the mall.

鈥淗e was just shooting it,鈥� she said of the spray that left everybody coughing and gagging.

Then she heard more glass breaking.

She was thankful the robbers didn鈥檛 use guns.
