POLICE in Calderdale have received a large number of complaints over mini-scooters being ridden illegally.
It is thought many parents bought the scooters, or Go-Peds, as Christmas presents - but they should not be used on roads or pavements.
Sgt Garry Alderson, of Calderdale police's road traffic department, said: "Parents have been buying mechanically powered scooters as presents for their children. Some people see them as ideal gifts, but they are not toys.
"Parents buy them with the best of intentions, without perhaps realising the legal implications.
"I am concerned that some people do not realise you need a driving licence, insurance and a helmet to use one of these scooters.
"There are also other restrictions. They can, for instance, only be used on private land. This does not include public parks," said Sgt Alderson.
"While these scooters are great for young people - and I don't want to spoil anyone's fun - riders must comply fully with regulations.
"They must make sure, while on private land, that they are doing so with the owner's permission.
"It is important people are aware of the impact they have on others and that they don't use the scooters in an anti-social or dangerous way."
Peter Shepherdson, Calderdale Council's road safety officer, said: "Many people who have difficulty walking are terrified of being knocked down by a cyclist on the footway.
"This is with good reason, as some have been injured. One lady ended up with a broken leg.
"These scooters are faster and heavier than bikes and injuries they cause can be much worse," added Mr Shepherdson.
