GRAND HAVEN TOWNSHIP, Mich. (WZZM) --Thirty business break-ins in Ottawa County are all tied to the same suspects, according to investigators who say the thieves are now targeting a larger area.

Over the weekend, five businesses were targeted in Grand Haven Township, four of them in a shopping center off U.S. 31., including a Mancino's restaurant.

"You feel violated you know, because it's such a small trusting community," says Bryce Weenum, whose father owns Mancino's.

Weenum showed WZZM 13 surveillance video of the break in.
The video shows the masked suspects stealing from the cash register then heading to the back room, where they hammered away at the safe. One of them looks up, as if confused.

"I can't even put into words how upset we are," says Weenum. "This is more than a break-in, this is a vendetta."

"The worst part is we all felt so secure here this is our home away from home," says Jaclyn Dailey, an employee at Mancino's.

Unlike in a lot of break ins where the suspects try to get in and out as soon as possible, in this case it appears they were taking their time. In fact, Weenum says the suspects even stopped by the cooler to get a drink.

Investigators believe the same suspects have broken into at least 30 other businesses, including in Holland Township last month.

"From other video surveillance from other businesses they (the suspects) were in businesses for a very short amount of time, in the case you mentioned (Mancino's), they were in there for an extraordinarily long period of time," says Lt. Mark Bennet, with the Ottawa County Sheriff's Department.

"It shows they're getting comfortable and arrogant with this, so hopefully they'll make a mistake soon," says Weenum.

Mancino's is planning to make changes to its security system.
However, it's still open and will continue to deliver pizza's the same way.

The suspects got away with an undisclosed amount of cash.
