The cop yelled, "He's stabbing me, shoot him," moments before Mohamed Bah was gunned down, the revised lawsuit will allege, citing official reports on the Sept. 25, 2012 incident.
The shooting occurred in Bah's apartment after his mother phoned 911. She claims she wanted an ambulance for her son because he seemed depressed.

Lawyers for Bah's family said Monday they were filing new allegations in a lawsuit brought against the city this September.

Before officers fired 10 shots at Bah, killing him, Sgt. Joseph McCormack struck Det. Edwin Mateo from behind with a Taser gun, causing Mateo to shout out, according to the amended lawsuit.
In addition to the new claim about why Bah was shot, the revised complaint will allege that Bah was alive after he was shot and that he was disrespectfully dragged along the ground as authorities brought him down from his fifth floor apartment to a waiting ambulance.
Photos snapped the next morning show long trials of smeared blood in the hallway of Bah's building, according to his family's lawyers.

The family has also been told that Bah's knife was lost during Hurricane Sandy, the lawyer said Monday.
The amended lawsuit seeks $70 million in damages and a court order forcing the NYPD to change the way it responds to 911 calls that involve emotionally disturbed people.
"First, they respond to his mother's call for help by treating Mr. Bah like a criminal, then make a series of critical errors and, after shooting him, treat him worse than they would treat a wounded animal," Bah family lawyer Randolph McLaughlin said in a statement.
"The case involves tragic circumstances. The Law Department hasn't seen the amended complaint. We'll evaluate the matter thoroughly."
