Two students were stabbed and another was injured in a "serious assault" that saw cruisers descend on Brock University Thursday night and briefly closed its campus.

Niagara Regional Police were called to the school around 8 p.m for what was initially reported to be a shooting, media relations officer Phil Gavin said in tweets.

Brock Campus Security tweeted it was investigating an incident together with Niagara police at Village Residence, located on the southwest end of the campus.

Officers arrived to find three male students in their twenties injured near the residence. Two had non-life threatening stab injuries. The third had a non-life threatening injury from a struggle with the suspects, police say.

The victims have been treated and released. The weapons used have not been recovered by police, Gavin said.

Police are looking for two suspects. One is a slim man in his 20s, possibly of East Indian descent, wearing a dark toque, dark clothes and a dark mask covering the low portion of his face, police say. The other is also slim and in his 20s, also possibly of East Indian descent, but was wearing light coloured clothing and possibly grey pants. Police haven't released a description of the getaway car.

Anyone who witnessed the incident is asked to contact police.

Students and staff were advised they could move freely around campus but that they should steer clear of the police investigation. Classes will resume as usual Friday, the school said.

Following speculation online about a possible "active shooter" on campus, Niagara police took to Twitter to dispel the rumours.

School officials say they will be reviewing with campus security how details of the incident were communicated to students Thursday night.
