Authorities arrested a suspected serial bank robber who allegedly robbed banks along the East Coast, including several in New York and New Jersey, the FBI said. 

 

Luis Alomar, 37, was taken into custody in Medford, Long Island early Tuesday. 

 

A federal arrest warrant had been issued for him in Delaware for a bank robbery he allegedly committed in the state, and the FBI had warned he may be armed and dangerous.

 

Authorities say Alomar would allegedly walk into a bank or store and demand money. In most cases, they say he handed a note to the teller indicating he had a weapon; in other cases, a weapon was displayed. 

 

Alomar allegedly made verbal threats to bank tellers, telling them he would shoot them if they contacted police, authorities said. 

 

The FBI, Suffolk County, Westchester, Yonkers and Greenwich, Conn., police departments and New York State Division of Parole assisted in the arrest.
