PEOPLE who have received mobile phones as Christmas presents have been urged to make them thief-proof.
They are urged to record their phone's identification number, which can then be used to render the phone useless if it is stolen.
Pc Dave Mc- Sweeney, of Huddersfield, said: "Many people, especially children, will have received phones as presents. But they should take heed of crime prevention advice.
"Don't give the thieves a chance. Make sure your phone is kept safe."
He urged youngsters not to flash their phones around and be careful where they use them - not in busy places where they don't know who is around.
Many people have phones snatched during conversations by opportunist thieves.
Pc McSweeney urged everyone to record their phone's IMEI (International Mobile Equipment Identity) number and register it with the phone's operator.
If the phone is stolen, the victim tells the operator and the phone can then be barred, making it useless.
Pc McSweeney added: "It is important that any would-be robbers know that a stolen phone can be made useless within seconds - so what is the point in risking jail for nothing?"
* To find out your phone's IMEI number, tap *#06# into it and the 15-digit serial number will appear on the screen. Make a note of it and keep it safe.
