Adele Apologizes After Fan Is Injured at Concert in Scotland

The singer tweeted, "It won't happen again."

"I'm so sorry to hear that someone got hurt at my show tonight. It's being investigated to ensure it won't happen again. X," she tweeted Friday evening.

According to the venue, SSE Hydro, a woman was injured during the British singer's sold-out show.

"I can confirm that on Friday evening's performance a chain fell from the production rigging above on to a member of the audience," a rep for the venue told ABC News.

"The lady was attended to by our own medical team and then taken to hospital as a precaution," the statement continued. "The safety of every member of our audience is paramount and we are currently working with the promoter's production team to establish why this happened and to ensure it does not happen again."

Adele is currently on her "25" tour. She starts her U.S.-leg of the tour on July 5 in St. Paul, Minnesota.
