A young man was taken to hospital as a priority after a suspected stabbing in Hounslow on Friday (August 22) night.
Police have since said two men were taken to hospital with multiple stab wounds. Both have now been discharged.
Paramedics were called to Chapel Road, near the junction with Hanworth Road, just south of Hounslow High Street, just after 9pm, to reports of a stabbing.
A spokeswoman for London Ambulance Service (LAS) said a young man, believed to be aged in his teens, was taken to hospital 'as a priority'.
She said it had sent a single responder in a car and an ambulance crew to the scene.
It is not known at this stage what condition the man is in or whether he remains in hospital.
Police have yet to confirm details of the incident, but if it is a stabbing as reported it would be the latest in a spate of knife attacks in the borough.
On August 12, a man was stabbed in Hounslow over a mobile phone, before good samaritans bravely chased the attacker away. Eight days earlier a man in his early 30s was found stabbed in Chiswick High Road.
Those incidents followed four stabbings in the space of a month during April and May this year, including the fatal stabbing of Jamil Palmer, for which five teenagers are due to stand trial this November.
