Gov. Sean Parnell has signed legislation aimed at cracking down on the abuse of children and child exploitation.

House Bill 127 also expands state stalking laws to take into account new technologies used by stalkers, such as installation of a global positioning system to follow someone.

In a statement, Parnell said it's the state's obligation to put the safety of its children first. He said he appreciated the unanimous support from the Legislature in helping to fight against those who harm children.

Parnell also signed a measure, sponsored by Sen. Kevin Meyer of Anchorage, that increases the penalties for a registered sex offender or child kidnapper who provides alcohol to someone younger than 21.
