GLENDALE, Ariz. — Barclays Center issued a statement on Friday outlining new measures for its staff and patrons at Islanders games following an altercation in the stands during Tuesday’s game.

“On Tuesday night, December 15, there was an altercation during an Islanders game when arena staff tried to restrict guests from accessing an unauthorized area,” the statement said. “Management immediately initiated an investigation, including reviewing all videos, meeting with staff and speaking to fans who were involved in, or witnessed, the incident. Law enforcement authorities were also notified of the incident. Any parties found to have acted inappropriately or in violation of arena policies, and of course the law, will be dealt with accordingly.”

Barclays Center is also implementing a five-point plan going forward:

*Reinforce security and guest services training with staff.

*Further communicate Barclays Center alcohol policies to fans, which includes two-drink-per-purchase limit.

*End beer and alcohol sales at the end of the second intermission.
