"Not only did Mr. Sterling lose his life, but my client also lost his liberty," Muflahi's lawyer, Joel Porter, told Reuters.
Muflahi had been allowing Sterling to sell bootleg compact discs outside the store, and had a friendly relationship with him. On Tuesday evening, Sterling was pinned face down by police officers and shot multiple times in the back, following law enforcement claims that a man had been threatening people with a gun.
"At all times defendants knew that plaintiff Muflahi was only a witness to the events at his store and that being a witness did not entitle police to hold plaintiff in custody or seize or commandeer his store and store equipment," the lawsuit states.
Muflahi is suing the two officers involved in the shooting, and two officers who are investigating the incident, as well as the chief of police
In several cities around the United States hundreds of people have been arrested protesting the police shootings of Alton Sterling and another man killed by police last week, Philando Castile, over the weekend, through Monday evening.
