Drake鈥檚 sprawling Toronto mansion was surrounded by police on Tuesday after a security guard working outside the rapper鈥檚 residence was seriously injured in an overnight shooting.

Toronto police were searching for suspects who fled in a vehicle and said it was too early to comment on a motive. Insp. Paul Krawczyk said he was aware of the headline-grabbing feud between Drake and rapper Kendrick Lamar but made no connection to it and would not comment further.

Krawczyk said he could not confirm if Drake was home at the time of the shooting, but he said the rapper鈥檚 team was co-operating with investigators.

鈥淚t is so early in the investigation that we don鈥檛 have a motive at this time,鈥� Krawczyk said in an update outside Drake鈥檚 mansion.

鈥淭his is no different than any other investigation. It鈥檚 maybe more high-profile because there鈥檚 more people here, but we treat it like any other incident.鈥�

Representatives for Drake did not immediately reply to a request for comment.

Yellow police tape fluttered in the breeze, cordoning off sections of the street outside the rapper鈥檚 home on Tuesday. Multiple police vehicles were seen in the area and officers could be seen walking around.

The shooting took place shortly after 2 a.m. outside Drake鈥檚 home in the affluent Bridle Path neighbourhood, police said.

Krawczyk said a security guard had been standing outside the gates at the front of the residence when he was shot from a vehicle that fled the scene. He said the guard was rushed to hospital in serious condition.

鈥淲e have individuals who obviously performed the shooting who were seen in a vehicle. I do not have a description of the vehicle or the suspects at this time,鈥� Krawczyk said.

He said he did not know whether the security guard was the target of the shooting or if the suspects tried to get into the sprawling mansion complex.

At Toronto鈥檚 Sunnybrook hospital, which is not far from Drake鈥檚 home, a volunteer on site said the security guard was in the critical care ward but a nurse said media weren鈥檛 allowed in the area. The volunteer said she had taken a police officer to the ward earlier in the day.

Police said they had collected video of the shooting but could not immediately identify the suspect vehicle. Krawczyk said police were dealing with 鈥渧ideo quality issues,鈥� and more information would be provided once they had a chance to analyze it further.

Asked about the shooting at an unrelated news conference Tuesday morning, Toronto Mayor Olivia Chow said she hopes police 鈥渨ill find the people that are violating the law and catch them.鈥�

鈥淎ny shooting is not welcome in this city,鈥� she said.

The shooting came as a long-simmering lyrical back-and-forth between Drake and Lamar escalated in the last week as both released tracks that included unsubstantiated allegations directed at each other.

Drake, born Aubrey Drake Graham, is one of the best-selling artists of the modern era. He鈥檚 released 13 No. 1 hits across his career, including 鈥淕od鈥檚 Plan,鈥� 鈥淲ork鈥� featuring Rihanna, and 鈥淥ne Dance鈥� with Wizkid and Kyla.

Lamar first poked fun at Drake in an appearance on a 2013 single and while the two traded barbs starting late last year, the public conflict ratcheted up in March.

That鈥檚 when rappers Future and Metro Boomin released their album 鈥淲e Don鈥檛 Trust You鈥� featuring several veiled Drake insults and at least one overt one in a guest appearance by Lamar. A month later, Drake issued a diss track that took jabs at all three rappers, particularly Lamar, who Drake implied is lagging behind his contemporaries.

Drake then posted another diss track on his Instagram that used AI-generated voices of Tupac Shakur and Snoop Dogg to goad Lamar. Lamar issued a track accusing Drake of having plastic surgery and calling him a bad father.

Late Friday, Drake dropped a track that alleges infidelity and accuses Lamar of abusing his fianc茅e. Less than an hour later, Lamar released a track suggesting Drake has a secret daughter. Another Lamar diss track was released overnight with an image of Drake鈥檚 Toronto mansion as the cover and had Lamar rapping specific personal insults, including an accusation that Drake is attracted to underage girls.

Drake issued a new track Sunday claiming he fed rumours of a secret daughter as bait, adding: 鈥淚鈥檇 never look twice at no teenager.鈥�

Drake was named Spotify鈥檚 most streamed artist of the decade, has won five Grammy awards, and is often credited for ushering in the new era of hip-hop where rappers sing.
