LEWISTON — Police are investigating whether the robberies of two local pharmacies on Sunday were connected.

“There were two pharmacies robbed today,” Maine State Police spokesman Steve McCausland said, “which brings the total for the year to, I think, 50” throughout the state.

Police are not releasing any details about an armed robbery at the Rite Aid Pharmacy on Lisbon Street, in which prescription drugs were stolen. Police have not released any details about the crime, including the time it occurred, and it is unclear whether the perpetrators were identified or apprehended.

Around 1 p.m., according to McCausland, the Rite Aid on West Gray Road in Gray was also robbed of prescription drugs. Weapons were again involved. The Cumberland County Sheriff’s Office responded to the crime, though they have not released any information about the incident.

Authorities are “looking at any similarities” between the robberies, said McCausland, because “there’s some suspicion they may be connected.”

Employees from both Rite Aid locations said they were not allowed to speak about the incidents.

The Lewiston Police Department did not respond to requests for information, and members of the Cumberland County Sheriff’s Office could not be reached for comment.
