Parents left a one-year-old baby beside a bin for over an hour while they queued to get on a ride at a theme park.

A horrified couple on a day trip with friends called security after they discovered a pram with a baby girl inside, parked near the Colossus ride at Thorpe Park on Bank Holiday Monday.

The buggy had been turned towards the fence while the parents, believed to be from West London and described as in their 40s, left to take their two other children on the rollercoaster.

Shock: Daniel Bevis, 22, who was on a day trip with his girlfriend (pictured together right) said he couldn't believe it when they realised the pushchair (right) was not empty, but had a tiny child inside

Daniel Bevis, 22, said he couldn't believe it when they realised the pushchair was not empty, but had a tiny child inside.

He alerted security and waited with girlfriend Casey McNamara, 22 and their two friends Connor Collins, 20 and Bryony Loft, 21, to make sure the baby was okay.

But shockingly when the parents turned up some time later, Mr Bevis said neither showed any remorse for their actions.

He told MailOnline: 'They had no regard at all for what they had done. They acted like they were embarrassed, as if they had just come to pick up a jacket they had left behind or something.'

Mr Bevis said the parents didn't apologise or thank the the group of four, whose day was cut short.

The parents had decided to get into the 30-minute queue for the Colossus ride with their two other children.

Mr Bevis, an electric from Milton Keynes, said: 'It's horrifying — like the parents had no regard for their child. Anyone could have taken her.

Mr Bevis said: 'We stood with her for ten to 15 minutes. No one turned up so we called security. They took her to first aid then the parents arrived. They'd been gone over an hour.

'We confronted them — a mum, dad and three other kids, who'd been on the ride — but they had nothing to say.'

He described the parents attitude at 'horrifying' and when asked if they had anything to say he said, 'no, not at all'.

'They tried to walk out but security had a word with them and said it wasn't on,' Mr Bevis explained.

Surrey Police and social services were called and it is understood they will be getting a visit from the police in their local area.

But security staff told the group this happens 'more often than you would expect'.

A spokesman for Surrey Police said: 'The family's home force has been notified for a follow-up.'

The Sun reported that the parents claimed their elder daughter, aged 11, was supposed to be watching the child.

The £13.5million Colossus is one of the park's most popular rides and opened in 2002.
