Two brothers and a woman have been arrested in connection with an acid attack on a mother-of-six.
Carla Whitlock suffered serious burns following the incident outside the Turtle Bay restaurant in Southampton, Hampshire, on September 18.
Billy Midmore, 22, and 26-year-old Geoffrey Midmore, both from London, have been arrested along with a 33-year-old woman.
Detectives previously offered a £5,000 reward for information about the assault in a public appeal.
Detective Inspector Will Whale, leading the investigation, said: "We have had a tremendous response from members of the public, and we'd like to thank them for coming forward and speaking to us, and for sharing our appeals on social media."
The three suspects were arrested in Gillingham, Kent, at around 10.45pm on Monday and taken into custody for questioning.
A spokesman for Hampshire Police said: "We would like to thank the public and media for their assistance during this investigation."
Ms Whitlock has been released from hospital but has been told she may not regain the sight in one eye.
