A fan was reportedly injured at Adele's concert at the SSE Hydro Arena in Glasgow, Scotland, on Friday.
"Wife is currently in hospital due to stage rigging falling on her!" Martyn Duncan tweeted from his account, @MartynD83, at around 1 a.m. Western European time. "Disgusted at lack of support from SSE hydro! @TheSSEHydro @Adele."
Duncan also retweeted several reports about the incident.
A spokesperson for the venue gave a statement to the U.K.'s Daily Record, saying that a concertgoer was struck by a chain during the first of Adele's two shows at the 13,000 person venue.
"A chain belonging to the production came down and hit one person who was taken to hospital as a precaution," the spokesperson said. "We are liaising with the production crew to ascertain what happened. This is all we know at this stage."
Adele herself later tweeted an apology, noting that the incident was being looked into.
"I'm so sorry to hear that someone got hurt at my show tonight," the singer wrote. "It's being investigated to ensure it won't happen again. X."
