New law to tackle stalking introduced

Stalking has become a specific criminal offence in England and Wales in a move to improve victims' safety.
The government has introduced two offences, stalking and stalking involving a fear of violence.
Campaigners had long claimed dealing with stalking under existing harassment laws was inadequate. In Scotland stalking was made an offence in 2010.
