Police are searching for suspects in the armed robbery of a burger joint Wednesday morning.

Police say two employees at Pat's Hubba Hubba restaurant were held up by four gunmen right before the restaurant was about to close. Employees say the gunmen jumped over the counter, took the cash from the register, and smashed the phone.

Police believe the robbery may be connected to three others that happened this month. These include one at Stamford's Garden Catering and one at Chin's Restaurant. Police have made arrests in the other two robberies.
