Amid the unrest in Ferguson, Mo., a second police-involved shooting was reported overnight, Fox 2 Now reported.

Around 1 a.m. on Wednesday, St. Louis County police responded to reports of shots being fired and four or five armed suspects, wearing ski masks, running near the intersection of Chambers Road and Sheffingdel Court in Ferguson, Valerie Schremp Hahn, a reporter for the St. Louis Post-Dispatch, reported.

Officers arrived on the scene, saw "multiple subjects running" and gave chase, police spokesman Officer Brian Schellman told the St. Louis Post-Dispatch.

Upon approaching one of the suspects, the man allegedly pointed a handgun at the officer, police said. In response, the officer opened fire.

A gun was reportedly recovered at the scene.

The suspect, who was critically wounded, was taken to an area hospital. The officer was not injured.

There is no word yet on the location of the other suspects.

Since the fatal police shooting of Michael Brown, an unarmed teen, over the weekend, Ferguson has seen large protests, clashes and looting.

St. Louis County Police told KMOV journalist Mike Colombo that this latest shooting was separate from the "Ferguson detail."
