NEW YORK (CBSNewYork) – Police in Brooklyn are searching for the suspects behind three armed robberies in 10 days.

They allegedly targeted two stores and a food deliveryman between Feb. 13 and 23 in Cypress Hills.

In the first incident, police said the suspects held up A&E convenience store on Jamaica Avenue. They made off with money from the cash register and the 19-year-old clerk's pocket, along with his cellphone.

Four days later, one suspect allegedly robbed a 50-year-old deliveryman on Hendrix Street, striking him in the head with a gun and stealing his money, cellphone and electric bike.

Most recently, police said a suspect held up XYZ Smoke Shop on Fulton Street and got away with money, two cellphones, an iPad and watch.

Surveillance videos show the suspects beat the deliveryman with a gun and pull a weapon on the 17-year-old clerk in the last incident.
