HELENA, Mont. -

Legislators are looking at a number of human-trafficking measures in response to alarms over reports of increased prostitution near the Bakken oil fields.
    
House Bill 218 is aimed at preventing child-sex trafficking in eastern Montana by funding counseling, training and education programs in communities there.
    
Three other measures are designed to punish perpetrators and grant victims access to assistance.
    
House Bills 478 and 488 have both passed the House and need the approval of the Senate. Both chambers have endorsed Senate Bill 259.
    
An advocacy group called Polaris says Montana's human trafficking legislation is lagging compared with other states.
