Detectives in Sefton, Merseyside, are appealing for information following a robbery at the Esso filling station in Waterloo on Monday, 12 October.
At around 10.45pm, police received a report that a robbery had taken place at the filling station on College Road. Three offenders entered the premises and restrained a member of staff before taking a quantity of cash and cigarettes.
The offenders also stole a silver Vauxhall Vivaro van from the scene which was later recovered.
The 34-year-old member of staff was unhurt but left extremely shaken by the incident. He managed to raise the alarm and emergency services attended.
One of the offenders is described as having his face covered and wearing dark clothes and black gloves.
A full investigation has been launched and house to house enquiries have been carried out. CCTV opportunities are also being explored and the scene has been forensically examined.
Detective Inspector Mike Dalton said: “This was extremely frightening for the victim, who was just trying to do his job.
“Incidents like this are extremely rare and we are working hard to trace the three offenders responsible.
“The force is absolutely determined to crack down on attempts to rob businesses across Merseyside and we are continuing to run a range of proactive initiatives to help them improve security.
“I can reassure people we are doing everything we can to trace and arrest the offenders. We’d appeal to anyone who may have seen anybody acting suspiciously in the area last night or witnessed any part of the incident to get in contact.
“This incident happened near to a busy fast food outlet and I’m sure someone will have seen the offenders before the incident or saw the vehicle driving off afterwards.”
Anyone with any information about this incident is asked to contact Sefton CID on 0151 777 3055 or Crimestoppers anonymously on 0800 555111.
