WESTPORT — Two New York men suspected of working together to rob banks across the state and in Rhode Island were arrested in Westport early this week, following similar charges in nearby towns.

Alpha Jalloh, of New England Thruway in Bronx, N.Y., allegedly committed the spree of similar bank robberies working with an alleged accomplice, Loang Manpign, of Bronx, N.Y. Both men were picked up in New York late last month and extradited to Connecticut, police said. Jalloh, 24, was arrested by Darien Police last week, while Manpign, 24, is already facing Waterbury charges.

On July 2, Jalloh allegedly passed a note to a bank employee saying a robbery was underway and that he had a gun just before 1 p.m. at TD Bank, 1111 Post Road East in Westport. Manpign allegedly drove Jalloh to and from the bank, knowing he would commit a robbery.

Westport Police connected the robbery with a similar crime in Darien — the June 12 robbery of a Chase Bank in the town — and detectives from both departments worked to connect the crimes, according to police.

Jalloh has also been linked to bank robberies in Waterbury and Pawtucket, R.I. Detectives believe Manpign knowingly collaborated as Jalloh’s driver for the string of crimes, Westport Police said.

Darien Police identified Jalloh as the suspect and, on July 27, the New York Police Department’s Fugitive Task Force stopped Jalloh’s car and arrested him based on Darien and Waterbury warrants for his arrest. Westport Police said Jalloh and his car passenger at the time, Manpign, were interviewed by detectives. They said Jalloh admitted to the Westport robbery while Manpign admitted to driving him to and from town for him to commit the crime.

On Aug. 14 Darien Police charged Jalloh with second-degree robbery, second-degree larceny and third-degree burglary with the inference of a firearm. He remains under investigation for a second robbery in the town — a July 11 robbery at a Chase Bank on Noroton Avenue in Darien.

Westport officers arrested Jalloh at Norwalk Superior Court Aug. 21, charging him with second-degree robbery, conspiracy to commit second-degree robbery and third-degree larceny. Manpign was arrested by a Westport detective the following day, Aug. 22, at Norwalk Superior Court. He was charged with conspiracy to commit second-degree robbery and conspiracy to commit third-degree larceny.

Both men were initially held on $100,000 cash bonds, but each was set to be arraigned on the day of their arrests.
