Four men and two women have been arrested in connection with a chemical attack that left a teenage woman with serious burns.
The 19-year-old victim suffered serious burns after a man threw cleaning fluid in her face in a doorstep attack.
It happened in MacDonald Close in Tividale, when she answered a knock at the door when the caller assaulted her with the caustic liquid, believed to be high-strength cleaning fluid.
She suffered 15 per cent burns to the side of her face and neck and is being treated in hospital after the incident which happened at about 3pm on Tuesday.
Doctors are also assessing whether she may have suffered internal injuries to her throat and lungs.
Three people have been arrested on suspicion of wounding, one person arrested on suspicion of conspiracy to wound and two people on suspicion of attempting to pervert the course of justice.
A man in his 60s who answered the door with the teenager also suffered minor burn injuries.
Police remained at the scene at the house last night which has been sealed off and a blue plastic sheet covered the ground floor bay window.
The cul-de-sac, where the attack took place, is largely made up of young families.
Those living just yards away from the police cordon spoke of their shock.
One mother-of-two, who didn't wished to be named, said: "I came home and I saw the first response car and presumed that a neighbour had fallen ill. Then I saw an ambulance and realised it was serious. I began to worry when the police arrived. It's horrific what has happened. I didn't know the people who lived there, they kept themselves to themselves like most people her but this doesn't happen around here. It's a lovely, quiet, family area. It's a massive shock."
Another resident said he came home to find the emergency services out his home, he said: "There were about four police cars, an ambulance, a fire engine and then later a forensic truck turned up. People haven't been told anything. They came home from work and there was police everywhere."
Anyone with information is urged to call Det Insp Jim Munro at West Midlands Police Force CID in Harborne on 101, or Crimestoppers anonymously on 0800 555 111.
