Two men are wanted by police in connection with the death of a woman who was hit by a car.
Alison McBlaine, 36, died in hospital on Thursday after she was hit by a Fiat Punto Grande which police believe deliberately mounted the pavement in Blackburn, Lancashire, at about 7.45pm on Tuesday.
Detectives investigating her murder are appealing for information to find Kaylib Connolly, 18, and Dean Qayum, 20.
A second pedestrian, a 26-year-old man, was also hit in the collision on Whalley Banks, at the junction with Pearson Street, and suffered serious injuries.
The car failed to stop at the scene and was later found on Lower Hollin Bank Street with significant front end damage.
Attempts had been made to set the vehicle on fire, a spokesman for Lancashire Police said.
Three people arrested by police remain in custody.
Detective Chief Inspector Lee Wilson said: "Connolly and Qayum are wanted in connection with this extremely serious offence.
"They know police want to speak to them and I believe they are being harboured in and around the Blackburn area at this time.
"I would warn anyone who is protecting them, or helping to hide them, that we will identify this during our investigation and they will also be arrested and prosecuted.
"My thoughts and those of the team engaged on this inquiry remain with Alison's loved ones, in particular her 12-year-old son Reagan.
"I would urge anyone with information about what has happened, or who knows where Connolly and Qayum are, to do the right thing - please come forward and speak to police immediately.
"We will not stop in our efforts to find both men and I would urge the public to help us find those responsible for this brutal and callous attack."
