Three children remain in hospital after Sunday's roller coaster crash at M&D's theme park.

Ten people were taken to hospital after the carriage came off the rails on the Tsunami coaster at the amusement park in Motherwell, North Lanarkshire, at the weekend.

Five gondolas derailed as they were rounding a bend and plunged to the ground, trapping several people and colliding with a children's ride.

NHS bosses confirmed on Wednesday that three youngsters are still being treated in the Royal Hospital for Children following the incident. Two of them remain in a serious condition and the third is stable.

It was also revealed the Tsunami passed its annual independent safety inspection earlier this month and was closed the day before the crash due to a minor electrical fault.

The owner of the theme park said all rides are safety checked on a daily basis and added his "heart goes out to" all of those involved.

Douglas Taylor, director of M&D's, said: "Each and every ride within the theme park is safety checked on a daily basis and undergoes a thorough independent inspection every 12 months.

"Tsunami had its annual independent safety inspection in early June.

"My brother Matthew and I have been in business together for 50 years and this is the first incident of this type that we have ever been involved with.

"We are devastated both as a family and a business and our heart goes out to everyone who has been affected by the accident."

Police working on the investigation into the incident have set up a dedicated email address for witnesses to send pictures and footage of the crash. The address is rollercoaster@scotland.pnn.police.uk.

A statement said: "Police continue to appeal to anyone who was within the park during the time of the incident and who may have footage or images, either on mobile phones or cameras, to send them directly to the dedicated inbox."

Liam Boyle, 11, underwent surgery to save his badly injured hand. His grandfather, Thomas Campbell, from Glasgow, said on Facebook: "The good news is Liam's operation has been a success.

"They have saved his arm and hand. Recovery will take a while but at least we know he's going to be alright. Thanks for all the support, much appreciated."
