M&D's theme park has been forced to apologise after a billboard for a new ride appeared in South Lanarkshire displaying the words "Bring on the fear".

The advertisement for the Giant Condor attraction appeared on a street in Hamilton just weeks after one of its roller coasters derailed leaving several people seriously injured.

Eight children and two adults were taken to hospital after the Tsunami ride derailed and plunged 20ft to the ground on Sunday June 26 at the amusement park at Strathclyde Country Park, Motherwell.

Three children were said to be in a serious condition.

A spokesman on behalf of M&D's said: "All of our planned advertising campaigns were cancelled in the immediate aftermath of the Tsunami accident.

"An error by our billboard advertising agency ClearChannel resulted in this advert appearing on a single site.

"We ordered its removal as soon as we were alerted to it and ClearChannel has assured us that its mistake will not be repeated.

"We would like to apologise for any distress caused."

According to the M&D's website, The Giant Condor is the only one of its kind in Europe.

The advert says: "You can soar into the sky to over 30 metres in 28 custom built gondolas built for two.

"It's big, it's very scary, it's The Giant Condor."

The theme park's rides were reopened on Friday after being shut down since the derailment.

The Tsunami will remain closed but M&D's said all other rides have been tested and the reopening of the park approved by the Health and Safety Executive (HSE).

A spokesman said: "All of the rides have undergone thorough independent testing and, following dialogue with the HSE, the theme park has now reopened to our customers.

"Safety remains our paramount concern and each and every ride will continue to be safety-checked on a daily basis. The Tsunami remains closed until further notice."
