The family of Scott Hutchison, the singer-songwriter behind Scottish indie-rock band Frightened Rabbit, have reported him missing, the BBC reports. Hutchison, 36, was last seen Wednesday morning at the Dakota Hotel in South Queensferry, Scotland, around 1 a.m. UK time. He is believed to have left for the nearby city of Edinburgh, where police are appealing for information on his whereabouts.

Late Tuesday night, Hutchison posted a pair of tweets raising concerns over his welfare:

The band later appealed for information:

Inspector Graeme Dignan told the BBC: “We are keen to locate Scott as soon as possible to ensure he is safe and well and would urge anyone who can assist with our ongoing inquiries to come forward. If you believe you have seen him since the early hours of Wednesday morning or know where he currently is, then please contact police immediately. I’d also urge Scott to get in touch with family, friends or with police, to let us know he is alright.”

Hutchison was last seen wearing “a dark baseball cap, navy blue hooded jacket, grey or khaki trousers and white trainers,” according to the BBC.

On Thursday, police renewed calls for information, attempting to identify two people seen crossing a nearby bridge shortly after Hutchison was last seen:

Frightened Rabbit have released a string of well-received records in the last 12 years, including their 2008 breakout, Midnight Organ Fight. After their latest release, 2016’s Painting of a Panic Attack, Hutchison had indicated a new album is under way. He also released a solo record called Owl John in 2014 and, last month, an album with Editors and Frightened Rabbit members, under the name Mastersystem.
