Millions of children will miss out on Hallowe'en fun because their parents are too terrified to let them out, a new survey revealed yesterday.

Knife crime and violence means parents feel it is more dangerous for children to trick or treat now.

And more than half of parents in the poll said they were keeping youngsters indoors rather than let them go trick or treating on Friday. They cited dangerous roads, antisocial behaviour, bullying and drinking as the main reasons.

The results came in a poll by the Children's Safety Education Foundation (CSEF).

It asked 460 parents for their opinions on Hallowe'en.

Results showed 54% of parents will ban their children from taking part in the age-old tradition, with 45% citing road safety issues and 43% highlighting antisocial behaviour as a concern. And of those who will let their children out, 89% will be accompanied by an adult with 72% saying they will only allow their children to visit friends and neighbours they know.

But, despite the fears, the same survey revealed only 3% of children have actually been involved in an accident or crime while trick or treating.

John McNamee, chief executive of CSEF, said: "It's encouraging to see that the vast majority of children who are going trick or treating will be doing so under supervision.

"This really is key to ensuring a successful and fun Hallowe'en for children, parents and residents alike."

CSEF recommend children should be accompanied by an adult at all times while trick or treating and to restrict visits to friends and family. Other advice includes ensuring costumes are flame-retardant.
