BRIDGEPORT -- Police said a local man apparently dissatisfied with his take from robbing a Subway restaurant Thursday went back and robbed it the next day.

Luis Valentin, 40, of Sherman Street, was charged with first-degree robbery and conspiracy to commit first-degree robbery for the holdup Friday of the Subway sandwich shop on Barnum Avenue. Police said they are getting a warrant to arrest him for robbing the same restaurant the day before.

According to police, on Thursday, Valentin, armed with a knife, went into the restaurant and demanded money. He left with a small amount from the cash register, they said.

The next day, police said, Valentin was concerned that he didn't get enough from the first robbery and persuaded a friend, Augustine Rodriguez, 22, to go back with him.

Police said the two men entered the Subway and Valentin rapped the knife against the door and announced it was a robbery.

The two men were given about $250 by a restaurant employee, police said, but on the way out Valentin went up to a male customer and ordered him to turn over his money. Valentin and Rodriguez then ran out to a waiting van.

A short time later, police said, officers spotted the van on Kossuth Street. They pulled it over and arrested Valentin and Rodriguez.

While in custody, police said, both men confessed to taking part in Friday's robbery, but each claimed the other instigated it.

Rodriguez was also charged with first-degree robbery and conspiracy to commit first-degree robbery. Both men were being held in lieu of $100,000 bonds.
