Adele has promised a full investigation into an incident that left a fan injured at her concert in Glasgow, Scotland.

Overhead rigging fell on the gig-goer during the Hello singer's performance at The SSE Hydro on Friday night (25Mar16).

Details about exactly what happened and the identity of the fan are still hazy but reports suggest a chain hit the person in the face, leaving him or her bloodied.

The fan was taken to a nearby hospital as a precaution, and Adele wasted no time in commenting on the incident.

Shortly after she was told about what had happened after she left the stage, the singer tweeted: "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."

A spokesperson for the arena told the U.K.'s Daily Record, "A chain belonging to the production came down and hit one person who was taken to hospital as a precaution. We are liaising with the production crew to ascertain what happened. This is all we know at this stage."

The gig was the first of two Adele has booked at the 13,000-capacity venue.

The superstar has been grabbing headlines all week for her concerts. At her Glasgow show, she invited a fan onstage and signed his chest at his request, with the listener explaining he hoped to tattoo her signature on his body the next day.

And on Tuesday (22Mar16) while performing at the O2 Arena, she took a few questions from the audience, and when one fan brought up motherhood and breastfeeding, Adele went off like a rocket.

The 27-year-old singer said, "You know what, the pressure on us is f**king ridiculous. (There's) no worse people who put pressure on (sic). You can go f**k yourselves, alright? Because it's hard. Some of us can't do it!"

She then opened up further about her struggles with her three-year-old son, Angelo, adding, "All I wanted to do was breastfeed my kid and then I felt like, if I was in the jungle right now, back in the day, my kid would be dead because the milk's gone... It's not funny!"
