Gunmen have robbed three Akron businesses in different parts of the city since Monday, police said.

It’s unclear if the heists in West Akron, Kenmore and Wallhaven are connected.

The most recent robbery occurred about 3 p.m. Tuesday when a gunman walked into Copley News, pointed a weapon at a clerk and demanded money, police said.

The clerk handed over cash from the register and the gunman left the shop — a convenience store in a small plaza on Copley Road near Orlando Avenue — and was last seen walking west on Copley Road about 3 p.m., police said.

The day before in Kenmore, the Boost Mobile store in the 2200 bock of East Avenue was robbed about 10 a.m.

In that case, a clerk approached a man looking around the store and asked if he could help him find something. The man then demanded the clerk hand over money. The clerk reported seeing a handgun tucked into the robber’s waistband.

After the clerk gave the thief money from a register, the robber fled and got into a four-door, gold Mitsubishi parked on a side street, police said.

Finally, just before 9 p.m. Monday, a man walked into the Subway restaurant in the 1500 block of West Market Street, pulled out a gun and demanded money. An employee gave the robber money, and the man fled.

No one was reported injured in any of the robberies.

The description of the suspects in each case varies, although the man who held up the Subway may have had a scar near his right eye.

Police ask anyone with information about any of the robberies to call detectives at 330-375-2552.
