Terrace RCMP are asking for witnesses to come forward after two stabbings earlier this week.
Police were called to the first incident at about 9:45 Wednesday night when they received reports of someone being chased with a knife.
Officers arrested a man in the 2600 block of Sparks Street and found a man and woman suffering from serious, but non life-threatening injuries.
Mounties were then called to the hospital at about 3:45 a.m. Thursday after a man arrived with stab wounds.
The man told police he was stabbed in the back while in his tent west of the Sande Overpass. Investigators say the attack was unprovoked and the victim did not know his attacker.
Contact Terrace RCMP or Crime Stoppers if you have information about either incident.
