Montgomery County Police are searching for suspects in four smash-and-grab robberies at four different businesses early Tuesday morning.

All of the break-ins happened around 3 a.m. at businesses in Maryland shopping plazas.

The earliest reported incident happened at the Dunkin' Donuts at the Cabin John Mall in Potomac around 2:50 a.m.

At around 3:07 a.m., the Dunkin' Donuts, the Dollar Plus Shop, and the Little Caesars at a shopping plaza on the 13000 block of New Hampshire Avenue in Silver Spring were broken into.

The owner of the Dunkin' Donuts in Silver Spring told FOX 5 that the same business had been broken into two weeks ago.

At this time, the owner of the Dollar Plus Shop say it does not appear anything was taken from the store.

In all of the robberies, the suspects quickly broke in and exited the locations.
