BRIDGEPORT - Bridgeport police say a man is under arrest for a series of robberies.

Police say Michael Ramos, 32, robbed Wireless Wizard of thousands of dollars last Wednesday. Then, on Monday, they believe he walked into a Payless on Boston Avenue, put on his mask, pulled out a knife and demanded money.

Police arrested Ramos later that evening and have linked him to an additional robbery in Stratford.

Ramos is being held on a $500,000 bond.
