Police responded Friday morning to a robbery report at a store in a west San Fernando Valley mall.

The robbery, possibly at a Neiman Marcus store, was reported at about 10 a.m. in the Westfield Topanga Mall. The report drew a large police and emergency medical response to the shopping center in Canoga Park.

It was not immediately clear whether any items were taken in the heist. The robbers were not armed, police said.

NBC4 is attempting to confirm whether anyone was arrested.

No injuries were reported.
