Five people were arrested and a dozen summonses issued following a melee on a Long Island Rail Road station platform in Rockville Centre early Friday, officials said.

Metropolitan Transportation Authority police arrested three people, while Rockville Centre police arrested two people, said MTA spokesman Aaron Donovan.

All of the summonses were for disorderly conduct, Donovan said. One MTA officer had his finger broken while helping a customer who was lying unresponsive on the platform and may have been intoxicated, Donovan said.

As the officer assisted that person, a man assaulted the officer and broke his finger, Donovan said.

Both people involved were arrested, Donovan said. The person who struck the officer was charged with assault on a police officer and resisting arrest. Their identities were not immediately available Friday.

Donovan said three people arrested by the MTA police were charged with disorderly conduct. One person was charged with resisting arrest.

The incident occurred at 2:19 a.m., Donovan said.

Donovan said MTA police have been assigned to patrol the platform beginning at 11:30 p.m. Thursday following a recent rash of incidents at the Rockville Centre station involving patrons leaving local bars.

"We've had previous incidents there," he said. "It's a relatively recent phenomenon, and it's raised concerns."
