Gunfire erupted outside a Chicago church after the funeral of a rapper, leaving at least six people wounded.

Police Sgt. Rocco Alioto says one person was critically injured when he was shot in the head Monday outside Bethlehem Star Missionary Baptist Church on Chicago's South Side.

Authorities say people were gathered at the church for the funeral of a rapper who had been killed about a week ago.

Police say four victims took themselves to local hospitals and two others who were more seriously hurt were transported by Chicago Fire Department paramedics.

Alioto says the man shot in the head was able to speak to police before being hospitalized with the non-life threatening injury.

Alioto said police arrived to a 'chaotic scene' with shell casing spanning two blocks. No one was in custody in connection with the shooting.

Aside from the man who was shot in the head, the victims' conditions have stabilized.

Authorities said a 25-year-old man was shot in the arm, according to the Chicago Sun-Times.

A woman, 27, was shot in the leg and lower body and another man, 24, was also shot in the leg.

The most seriously wounded victim is also a rapper, police told WLS-TV.

They were attending the funeral services for Vantrease R. Criss, 25, who was also known by his rapper name 'Dooski Tha Man.'

Criss was fatally shot on October 9 while he was walking with a woman on a Chicago street. The woman suffered a gunshot wound to the left foot.

Police have yet to make an arrest in connection with the October 9 shooting.

The Sun-Times quoted a man who lived within a block of where the shooting took place said that at first the gunshot sounded like 'rapid fire.'

'Then it sounded like cannon-fire,' he said, insisting on anonymity for fear that talking to the press would make him a target.

'I still have to live here,' he said.

The church pastor, Roosevelt Watkins, who was inside the church when the gunfire rang out, described the scene as 'pandemonium.'

'People ducking under cars, running for their lives, for safety, running back inside of the church, trying to get out of harm's way,' he said.

Ruth Rivera, who lives nearby, said: 'It sounded more or less like at least 40-50 gunshots from our backyard.

'And we came right away, there was gun shellings back here, there was blood on the floor.

'Right away the ambulance and the police came, immediately.'

Half a block away, police took at least three people who were stopped inside a silver car into custody, though it's unclear if it was related to the shooting in question.
