Toronto police have said a security guard was shot overnight outside the home of Canadian rapper Drake.
It comes amid his escalating war of words with US rap rival Kendrick Lamar.
Police said suspects in a vehicle shot the guard at the corner of the Park Lane Circle mansion around 02:00 EDT (06:00 GMT) on Tuesday before fleeing the scene.
It remains unclear if Drake was at home when the incident occurred or whether he was a target of the shooting.
"We are in contact with his team and they are cooperating," Inspector Paul Krawczyk of the Integrated Gun and Gang Task Force told reporters on Tuesday morning.
It is too early in the investigation to speak about a motive, he added.
He said police are currently assessing video that captures the shooting but are not releasing information about it due to video quality issues.
The victim is in hospital and is in serious condition, police said.
Witnesses told Canadian media he had sustained several gunshot wounds, including one to the chest.
The lyrical beef between Drake and Lamar has grown bitterly personal, with a flurry of "diss tracks" exchanged between two of hip-hop's biggest stars over the weekend.
The Canadian's house, in the ritzy Bridle Path neighbourhood of Toronto, is the subject of cover art for Lamar's song Not Like Us.
Pictures online show the property has been cordoned off with caution tape as police investigate the shooting.
