Scott Weiland, 48, died Thursday after he was found unresponsive in his tour bus while he and his band were set to perform in Minnesota, police said today.
As the Bloomington, Minnesota, Police Department continues its investigation into the singer's death, today the department issued a search warrant for the tour bus and found cocaine in the room where Weiland was discovered, police said.
"Detectives collected several items of evidence from inside the tour bus, to include a small quantity of suspected controlled substance that field tested positive as cocaine, in the bedroom where Mr. Weiland was located," police said in a statement.
Despite the discovery of the cocaine, "[t]here is no information at this time related to the cause of Weiland’s death. Additional information related to cause of death will be released by the Hennepin County Medical Examiner’s Office at a later date/time," police said.
Police also stated that "an additional small quantity of suspected controlled substance that field tested positive as cocaine, in the area of the tour bus known to be occupied by Thomas Delton Black, a traveling member of Weiland’s party."
Black was arrested on "Probable Cause Felony 5th Degree Possession of a Controlled Substance" and being held at the police department pending charges, according to police.
Weiland's band did not immediately respond to ABC News' request for comment on Black.
Late Thursday night, the singer's band Scott Weiland & The Wildabouts was scheduled to perform, but after first responders were called to the scene, "Officers arrived and determined the adult male was deceased," officials told ABC News at the time.
Today, Weiland's death was felt across the world of music.
The Stone Temple Pilots, the group with which Weiland first became a mainstream star in the 90's, took to Facebook and wrote, "The memories are many, and they run deep for us. We know amidst the good and the bad you struggled, time and time again. It’s what made you who you were. You were gifted beyond words, Scott."
Slash, the guitarist who played with Weiland in one of the singer's more recent groups Velvet Revolver, also took to Facebook and wrote, "Sad day," next to a classic image of the rocker performing on stage.
