Greater Manchester Police have launched an appeal for a man suspected of using a dating app to meet other men before attempting to steal their cars.
A victim in his 20s was stabbed a number of times on Tuesday evening after picking up the suspect in his vehicle.
The offender threatened the man as they were parked on the roadside and demanded he hand over his car keys before launching the attack.
The victim was taken to hospital with serious injuries.
The incident is being linked to two other carjacking attempts that occurred on Monday in Irlams o’ th’ Height, Salford and Prestwich.
Detective Inspector Gareth Jenkins, of Greater Manchester Police’s Salford district, said: “This is now the third attack following an attempted carjacking after an online dating app meeting and we’re working hard to find the man responsible.
“We have a CCTV image of a man we want to speak to as part of our investigation and I would appeal directly to the man to get in touch with us.
“We would also continue to encourage people using dating apps to always meet new people in public places and to let someone know where you’re going.”
Anyone with information should contact police on 0161 856 5194 or 101 quoting reference number 1764 of 26/03/2019.
