Three teenage boys have been stabbed in the Huddersfield area within 24 hours.
The first incident occurred at 2.30am on Saturday in Byram Street when two 16-year-old boys were stabbed in the abdomen.
They were taken to Leeds General Infirmary for treatment and have since been released.
Two local men aged 22 and 23 years old were arrested immediately following the incident and are in custody.
Then just after midnight on Sunday police were called to reports of a major disturbance following a private party next to Golcar Cricket Club in Swallow Lane.
Det Insp Seth Robinson of Kirklees CID said: “We received reports that there had been a major disturbance but when officers arrived there was no-one around apart from a 17-year-old youth from Quarmby who suffered a superficial knife wound to his abdomen.
“He was taken to Huddersfield Royal Infirmary and discharged this morning.
“Fortunately his injuries are minor and not life-threatening.
“We are searching for his assailant.
“I think it’s worrying that we have had two separate stabbing incidents in such a short time in two separate places and that we have youths clearly carrying knives.
“The implications can be tragic.
“The penalties are severe for people who carry knives.
“There are criminal consequences and there can be fatal consequences.”
