CHICAGO (WLS) -- It certainly was not the ending Dominiq Greer was hoping for.One minute he's proclaiming his fear of Chicago police and suing the city for $15 million, the next he's arrested for murder.No sooner had Greer announced he was suing Chicago police for shooting him without reason, was the 25-year-old arrested outside his attorney's office in the Loop.Investigators say Greer was wanted for a murder that took place May 27 inside a home on the 5600 block of South Wabash. Earlier however, Greer portrayed himself as an innocent victim of police brutality."I feared for my life because I see Chicago police do stuff every day to people," said Greer.According to the lawsuit filed Wednesday morning, Greer was shot by police without reason in the early morning hours of July 4, 2014 in Englewood.Private surveillance video shows Greer as he runs into an alley near 74th and Vincennes, carrying a gun.Greer throws the weapon in the air and that's when he is shot by police three times. Greer stumbles, gets back up, continues running and then falls again. The same officer shoots again.Greer acknowledged that he ran away from police after they approached him and two of his friends."They asked us to put our hands on the car. I told them no, so when they tried to grab me I ran. I feared for my life," said Greer."At no time did the officers see a gun in Mr. Greer's hand or the flash of a muzzle. There was no basis to shoot him three times and an additional four as he lay on the ground," said Eugene Hollander, Greer's attorney.A spokesperson for IPRA says their investigation into the matter was closed nearly a year ago after determining it was a justified shooting.Greer's attorney had no comment following his client's arrest Wednesday morning.
