Initial reports said a man had been shot, but police then said a gun dropped by a man running from police went off, and that no one was hit by a bullet. Earlier, Baltimore Police tweeted the man was shot "multiple times," but police later said no one had been shot.
A tweet by Baltimore Police read, "Shooting: 2500 block Marbourne Ave. Man reported to be shot multiple times. Southern District detectives investigating."
A witness told Fox News no words were exchanged between officers and the man, whom she described as "young" and possibly in his teens.
Police said the man's gun had fired when it fell during the chase. The witness, however, said she saw no weapon.
Police reportedly used pepper spray on the crowd after the shooting.
Last Friday, six Baltimore police officers were charged in the death of Gray, 25, who died April 19, one week after being injured while in police custody.
Gray's death touched off rioting, that culminated in the torching of 15 buildings and more than 100 cars one week ago.
The death of Gray led prosecutors to charge one police officer with murder, three with manslaughter and two with assault in the death of Gray, who a prosecutor said suffered a broken neck last month when he was left shackled at the feet and lying face down in a police van by officers who ignored his pleas as they made their rounds. Gray suffered a broken neck, apparently while riding in the back of the Baltimore police van.
