Linwood mosque shooting witness came 'within spitting distance' of man with shotgun spraying bullets at cars

A witness of a shooting at a second mosque in Christchurch says he came within spitting distance of a man with a shotgun spraying bullets at passing vehicles.

Dan is a courier driver and was doing a pickup in Linwood when he heard gunfire at about 1.45pm or 1.50pm.

"We initially thought it was a car backfiring but then the bangs became louder and more frequent, we thought well that can’t be a car backfiring," he told 1 NEWS while in lockdown following the shooting.

"Then I walked to the end of the road and came to the curbside within spitting distance of a man carrying a shotgun spraying bullets at a car going down Linwood Ave yelling and swearing at them."

"The guy walked away, I showed the cops where the gunman was."

The man said he spoke to a man who had come out of the mosque.

"He said they were all sitting there in a row on their knees doing their midday prayer."

"From what I understand from what he told me there was six gunmen, (who) came in and just started shooting and there’s at least four or five people dead inside."

Another person told the man that six people jumped out of a window at the mosque and got into a vehicle.

The man said police had swarmed the scene within a couple of minutes.

"From there it was a sea of cops."

Police have confirmed fatalities at the Linwood mosque and another Christchurch mosque.
