New details from the investigation into Scott Weiland's death reveal that drugs were found in the former Stone Temple Pilots and Velvet Revolver lead singer's tour bus, according to the Bloomington Police Department.
A search warrant was executed by police after the 48-year-old was found dead inside his tour bus in Bloomington, Minnesota, on Thursday night while on tour with his new band, Scott Weiland and the Wildabouts.
On Friday, the Bloomington Police Department issued a statement, revealing that evidence collected in the warrant included "a small quantity of suspected controlled substance that field tested positive as cocaine" inside the bedroom where he was found. The stimulant was also reportedly found in his bandmate Thomas Delton Black's bedroom.
Following the results of the investigation, Black, 47, was arrested and taken to the Bloomington Police Department, where he is being held pending charges for possession of a controlled substance.
Weiland's cause of death is yet to be determined, and additional details will be released at a later time, according to the police statement.
Weiland's former bandmates -- Eric Kretz and brothers Dean and Robert DeLeo -- penned a message to the late rocker on the Stone Temple Pilots Facebook page on Friday.
"Dear Scott, Let us start by saying thank you for sharing your life with us," the letter began. "Together we crafted a legacy of music that has given so many people happiness and great memories. The memories are many, and they run deep for us."
"We know amidst the good and the bad you struggled, time and time again," the post continued. "It's what made you who you were. You were gifted beyond words, Scott."
