ATLANTA — Atlanta police said at least one person is dead and at least four people have been injured in an active shooter situation on West Peachtree Street Wednesday afternoon.

Three of the victims have critical injuries. It’s unclear if all four people who were injured sustained gunshot wounds.

The shooter has been identified as Deion Patterson, age 24. Patterson is still on the loose and is considered armed and dangerous. Police said not approach him and to call 911 if he is seen.

Atlanta Mayor Andre Dickens confirmed that all five victims are women. None of them have been identified.

Police said no additional shots have been fired since the incident unfolded, but officers are still actively searching for the shooter and any other victims. The injured victims have been taken to the hospital. Their identities and conditions have not been released.

Atlanta police have released several photos of the alleged shooter pointing what appears to be a handgun inside a set of glass doors. He’s wearing a gray or black hoodie and carrying a bag.

Channel 2′s Michael Seiden was at the scene, where he saw what looked like hundreds of heavily-armed officers outside 1100 West Peachtree Street Northwest, which is a Northside Hospital facility.

Multiple agencies including Atlanta police, Atlanta fire, MARTA police, Georgia Tech Police and the Georgia State Patrol have responded to the situation.

Channel 2′s Mark Winne saw several ambulances speed away from the scene and said this is the largest police response he’s ever seen.

Police released the shelter-in-place orders in the area just before 3 p.m. but they are asking everyone to remain out of the area.

Police said that a driver was carjacked at the intersection of 14th Street and Williams Street not long after the hooting. The vehicle was initially reported to have been recovered, but police now say the vehicle has not been recovered.

Police have not given a description of the car and are working to learn if the carjacking is linked to the shooting.

Video circulated on social media of a man in similar clothing on top of the High Museum, but police said that person is a worker and was not involved in the shooting.

Atlanta Public Schools initially held students at Midtown and Washington clusters, along with Stanton Elementary, King Middle School, Wesley International Charter School and Dunbar Elementary School, but Atlanta Police have cleared them to release students.

Crime Stoppers is offering a $10,000 reward for information that leads to Patterson’s arrest. Information can be submitted anonymously to the Crime Stoppers Atlanta tip line at 404-577-TIPS (8477) or online at www.StopCrimeAtl.org .
