Suspects in a robbery of the South Street Mobile Station took more than money – they also made off with evidence that would implicate them in the case.

Sometime between 11 p.m. on Sunday, June 22, and 6 a.m. Monday, June 23, someone forcibly entered the Bow Mobil station, shutting off the alarm system before stealing cash and making sure the police wouldn’t see their faces.

“Once they were inside, they were able to force their way into the ATM and force cash out of that, and take cash from a safe in the store,” said Bow police Lt. Dave Girard. “They were able to take the computer responsible for storing the video surveillance as well.”

Girard would not comment if the department has any persons of interest in the investigation, but he said he has a small number of leads he will follow up on.

Despite not having any video evidence, Girard said he is confident investigators will be able to move forward toward making arrests in the case.

“Police have been able to solve plenty of crimes long before video surveillance, so there are a variety of other traditional police methods we’ll use,” he said. “We’re disappointed not to have the video, but there is still plenty we can do.”

Police are not yet sure if there is any connection between the Bow robbery and a number of other break-ins at gas stations in Merrimack Valley, as he said many similar crimes have taken place from the Bow area down to the North Shore of Boston.

Girard would not say how much cash was taken from the store, but compared to other thefts he has seen, he considers it a large quantity.

Based on the suspects’ ability to shut off the alarm and take the video recordings, Girard said it is possible it was an experienced robber.

“If someone is good at doing this, then yes, they are more likely to cover their tracks. But based on my experience, in any crime something is always left behind that can be used,” he said. “Anyone travelling South Street that day with information or that may have noticed anything should contact our tip line.”
