Screwdriver held to woman's head in robbery

A woman was allegedly assaulted and had a screwdriver held to her head during an armed robbery at a Christchurch bar this morning.

It was the second robbery to be reported to police within 45 minutes.

The Craic Irish Bar owner Marty Fuller said the staff member wasn’t injured but is "very shaken" by the incident on Riccarton Rd.

Mr Fuller said the woman was out back when she heard a noise about 10.30am and walked out to find a man behind the bar.

He said the man then assaulted her and forced her to hand over cash while holding a screwdriver to her head.

"She is very shaken. It would be scary for anyone," he said.

Police are investigating. 

It is the second time The Craic has been hit by armed robbers.

In 2013, two female staff members were held at gunpoint and forced to open the safe and pokie machines.

About 45 minutes after the Riccarton Rd incident, police were alerted to a robbery at an op-shop on Ferry Rd, in Woolston.

A police spokeswoman said the person was armed with a weapon but was unable to confirm what the weapon was and what was stolen.
