Masked robbers accosted Stony Brook University students off campus Tuesday night in two separate instances that have led authorities to beef up patrols on campus, university police said Wednesday.
In a safety alert to the campus community, police Chief Robert J. Lenahan said the victims were commuter students approached by two males in dark jackets and gloves.
No weapons were shown and Suffolk County Sixth Precinct detectives are investigating, authorities said.
The first occurred about 10:30 p.m. at Stony Brook Road and Memory Lane, with one suspect wearing a black and white mask, the alert said. Robbers, one wearing a green and red clown mask, struck again at 11 p.m. at Route 25A and Thompson's Hay Path, police said.
Each victim was walking alone when he was targeted, said Det. Sgt. Patrick Maher at the Sixth Precinct.
One had his wallet taken and incurred a minor knee injury when a robber pushed him to the ground, the sergeant said. He did not need to go to the hospital, Maher said.
The other victim was robbed of his Nike gym bag, Maher said.
Lenahan said security on campus will be increased. "We will be further enhancing our on-campus patrol coverage utilizing both uniformed and plainclothes officers," he said.
He noted that more than 100 "blue light phones" -- direct lines to police -- are spread across campus. He also urged people to get the university's "SB Guardian" feature, a one-touch speed dial that can be downloaded into a cellphone and gives the person's location to campus police.
Anyone with information may call Sixth Precinct detectives at 631-854-8652 or university detectives at 631-632-9884.
