UNLIKE the famous U2 line, shots did not ring out in the Memphis sky; this time it was western Sydney's turn.
Early on Tuesday morning residents in Granville, Merrylands, Northmead and Baulkham Hills witnessed five separate shooting attacks.
Homes in Harris Street, Merrylands, and Grimwood Street, Granville, were fired at while Infamous Ink in Pitt Street, Merrylands, and a shop in Baulkham Hills were also targeted.
The attacks are believed to be related to a feud between rival bikies the Nomads and Hells Angels.
A house and car at Pemulwuy were shot at on Saturday in what police say was a case of mistaken identity.
It is suspected the intended target was a neighbouring house.
Strike Force Kinnarra has been established in response to the most recent attacks and will be headed up by the gangs squad.
State Crime Commander, acting Commissioner Mal Lanyon, condemned the shootings.
"There is no doubt that these shootings are all about the conflicting groups sending a message to each other but they are reckless acts of violence.
"We also know there are members of these groups out there who don't agree with the violence being used.
"I encourage these people to provide that information to police.
"That information can be provided anonymously."
Witness John Paterson said he heard four shots just before midnight.
"At about 11.30pm I was half dozed then I heard this bang, bang, bang, bang," Mr Paterson said.
"They're the biggest pack of cowardly bastards. You get 10 or 20 of them with guns and they think they are big men."
A nearby resident of the Harris Street shooting, who asked not be named, said they feared for their children's safety.
"It sounded like gunshots about three or five times then a car sped off.
"I thought it was our house and I was worried because the kids were in the front room."
These latest shootings come after five earlier this month.
Merrylands police crime manager Adam Phillips said the main concern of police was for the public's safety.
"These are targeted attacks, criminal on criminal," Mr Phillips said.
"Our major concern is some innocent party will be injured or killed."
Police said the shooting of a house at Northmead was thought to be unrelated to these other shootings.
