Police arrested three suspects on Monday, following a month long investigation into a double stabbing in Niagara Falls.

The stabbings took place at about 2 a.m. on April 29 in front of Fallsview Casino Resort.

The victims, in their twenties, from Toronto, were treated on scene by paramedics and taken to a local hospital before being flown to an out-of-region trauma centre to be treated for serious injuries.

The investigation, which included the help of multiple police units, led to the arrests three men from the Greater Toronto Area — 22-year-old Piraveen Paramananthan of Toronto, 22-year-old Sugarshan Chandramohan of Uxbridge and 23-year-old Suvisan Chandramohan of Uxbridge. 

All three are charged with the alleged offences of three counts of attempted murder.

They attended a bail hearing at the Robert S. K. Welch Courthouse in St. Catharines on Wednesday.

Niagara Regional Police said the investigation remains ongoing with a possible fourth suspect outstanding, and are thanking the public, the ROPE Squad and the Toronto Police for their assistance in this investigation.
