Police say they are open-minded over the possibility that two Bristol stabbings are related.
On New Year's Day, a 15-year-old boy was stabbed repeatedly in Fishponds, Bristol, just a day after a 17-year-old was attacked in the city centre.
Officers are stepping up patrols in response to the incidents.
The latest of the two attacks happened at around 12:20pm on New Year's Day when two men approached the boy as he rode his scooter on Downend Road.
Police say the victim sustained "a number of stab wounds" before the men fled the scene.
Although the victim is currently in hospital, his injuries are not thought to be life-threatening.
Acting Detective Inspector, Mark Newbury said the force was keen to hear from anyone with relevant information.
He said: "Thankfully incidents of this nature are rare, but we're conscious a similar assault occurred in Bristol city centre in which a 17-year-old sustained a number of stab wounds on New Year's Eve.
"At this time the two incidents are separate investigations, but we are keeping an open mind as to whether they may be linked."
