A “swatting” incident in Kansas turned deadly when cops responded to the faux 911 call and shot an innocent 28-year-old man, it was revealed on Friday.

The tragedy unfolded when a “Call of Duty” player made a phony call to Wichita police after fighting over a bet at about 6 p.m. on Thursday, police said.

The prankster claimed he had just shot his dad and was holding his mom and brother hostage, Wichita deputy police chief Troy Livingston told reporters.

He then gave police the address of his nemesis.

When officers arrived, they surrounded the house where they were told a possible shooting had taken place.

Andrew Finch walked out the front door. He raised and dropped his hands multiple times before an officer opened fire, killing him with one shot.

Officers searched the house and found four people inside — none who had been shot or threatened.

Livingston called the “swatting” incident a “tragic and senseless act.”

“The irresponsible actions of a prankster put people and lives at risk,” Livingston said. “The incident is a nightmare for everyone involved including the family and our police department.”

Cops 1,400 miles away in Los Angeles on Friday arrested 25-year-old Tyler Barriss in connection to the deadly prank, an LAPD rep said.

Back in 2015, a 22-year-old man with the same name was arrested in Southern California for allegedly phoning in phony bomb threats to a local TV studio.

The Eagle newspaper of Wichita said the fake call stemmed from a feud over “Call of Duty.”

Gaming-industry news site Dexerto reported the argument was over a $1 or $2 bet.

The prankster put great detail in the deadly ruse, cops said.

“The calling party stated that he didn’t mean to kill his dad. He was arguing with his mom and things got out of hand,” Livingston said.

The officer who fired is a 7½-year veteran who has been placed on administrative leave. Livingston defended the officer, saying the cop genuinely feared the victim had a gun.

Livingston defended the officer, saying the cop genuinely feared the victim was reaching for a gun. Finch turned out to be unarmed.

“There were several commands given” by police, Livingston said.

“They were all consistent, ‘Put your hands up walk towards us.’ But he continued to drop them down by his waistband.”

Despite this tragic outcome, Livingston says his cops won’t discount 911 calls.

“When you call for help you’re going to get help. The officers have to respond accordingly,” he said.
