As we previously reported, on June 16th the stage at a Radiohead gig in Toronto collapsed, tragically resulting in the death of the band's drum technician Scott Johnson and injuring several other people.

Now Rolling Stone report that the companies behind the gig are being asked to comply with an investigation by the Canadian Ministry of Labour into the collapse. They include Ticker Tape Touring LLP, which is run by Radiohead themselves, along with concert promoter Live Nation, Optex Staging & Services and Nasco Staffing Solutions. They have been identified by the Ministry of Labour as being responsible for the incident, and the investigation is currently looking into which parties were responsible for what elements of the show.

"We're still trying to figure out who owns what, who's responsible for what," said Ministry of Labour spokesperson Matt Blajer to the Toronto Star. “You’ve got lighting technicians, sound technicians, the band’s people — we’re trying to figure out who worked for whom.”

Blajer confirmed that the Ministry had issued their orders "mainly to Live Nation", and that stage blueprints have been provided to the investigators already. It was emphasised that the investigation will "take time to unravel".
