A GANG of masked men snatched cash during a raid on Marks & Spencer Gemini.

The six men broke into the building on Europa Boulevard at 11pm on Friday.

A spokesman for Warrington police said: "They forced a number of tills and stole cash and a large quantity of gift vouchers."

The gang fled when they were disturbed by a group of night workers.

They escaped through one of the store's fire exits.

Detectives believe the men arrived via Burtonwood Services.

They all wore dark clothes and sleeveless fluorescent jackets with masks on and their heads covered.
