More area convenience stores fall victim to a group of thieves overnight.

Early Monday morning, Millcreek Police say suspects forced open a door at the Country Fair at Zuck and Zimmerly.

At least three thieves got in, and reportedly stole cigarettes.

This comes as Erie Police investigate a string of break-ins too, including one at the Country Fair at 26th and East Avenue, on February 6th.

In that case, Erie Police say four suspects smashed out a window, got inside and stole about 30 cartons of cigarettes.

Area agencies are working together to see if they're all connected.

Meantime, because of this string of break-ins, the owner of the Manus Sunoco convenience store at 12th and French Street in Erie says, they're on high alert, “It frightens the cashier that's on duty, most of the time they're young and they're very afraid of someone coming in here and sticking them up,” said Co-Owner Denice Manus.

Manus says they have security buttons, which alert police immediately, and only leave a small amount of cash in the register, especially when there’s a rash of break-ins like we’re seeing.

A group of thieves also broke into the Marathon gas station on Sterrettania road and Interstate-90 early Monday morning, State Police are investigating that one.

And Erie police are also investigating a handful of similar break-ins at city convenience stores from 2018.
