Two teenagers have been stabbed outside a college.
Police were called to the scene outside Manchester College at 11.10am on Thursday.
A 17-year-old boy suffered a stab wound to his chest and an 18-year-old man was stabbed in the back.
Both were taken to hospital and are receiving treatment for their injuries.
Officers from Greater Manchester Police (GMP) recovered a knife from the scene, in Chorlton Street in the city, and are appealing for anyone with information to come forward.
Chief Inspector Gareth Parkin, of GMP's City of Manchester team, said: "We currently have two people with serious injuries in hospital so it is imperative that anyone with information comes forward and helps us with our investigation.
"We have recovered a knife from the scene, which will be forensically examined but we still need people to contact us with any information that they have.
"I'd like to reassure the community that we have a number of highly skilled officers working on this investigation and will continue to carry out extensive inquiries."
