No sign of shopkeeper accused of brutal sex assault on woman with toddler

PENTICTON, B.C. - Police forces across B.C. and Alberta aren't making much headway tracking a Penticton, B.C. man accused of forcibly confining, beating and sexually assaulting a woman for more than 12 hours.

A Canada-wide warrant has been issue for 35-year-old David Wesley Bobbitt, who is wanted on a charge of attempted murder.

The 22-year-old woman was reported missing Saturday and was found by police beaten and tied up the next day.

Cpl. Dan Moskaluk says police have spoken to the suspect's family and acquaintances but they've provided very little information on his whereabouts.

The woman had gone to browse for second-hand furniture with her 22-month-old son when the attack occurred at Dave's Second Hand store, which Bobbitt operates.

Moskaluk says Bobbitt doesn't own a car and has been investigated for violent offences in the past.
