L.A. Kings superstar Jarret Stoll -- boyfriend of Erin Andrews -- was arrested in Vegas on suspicion on drug possession ... for allegedly bringing cocaine and ecstasy to a Vegas pool party.
According to local reports, 32-year-old Stoll was busted Friday at the Wet Republic pool party at the MGM Grand.
Stoll was reportedly taken into custody by the Las Vegas Metro Police Department. Unclear if Andrews was with him at the time.
Stoll was taken to Clark County Detention Center -- where he was booked. He was released on a $5,000 bail.
Stoll was clearly in Vegas to unwind after the Kings were eliminated from contention from the NHL playoffs.
The Kings have issued a statement saying, "We are aware of police reports out of Clark County, Nevada regarding Jarret Stoll."
"Our organization is concerned and has begun conducting a thorough internal investigation. While we continue to actively gather facts, we are withholding further comment at this time."
