Four people have been hurt after a BB gun was fired and a car driven at a crowd outside a pub in a "targeted attack".
A silver Volvo was driven towards the Gigmill pub on South Road, Norton, Stourbridge at around 10pm on Friday, police said.
The driver is understood to have got out of the vehicle and fired shots from a BB gun, hitting a man in the leg causing a minor injury.
He then drove the car towards a group standing on steps outside the pub.
A woman and the man, both in their 20s, suffered serious leg injuries and are being treated in hospital.
Their injuries are not believed to be life-threatening.
Two other women are also being treated in hospital for less severe injuries.
Police are now trying to locate the driver who fled the scene.
The area has been cordoned off and the Volvo is being seized for forensic examination.
Police are carrying out house-to-house enquiries and will look at CCTV.
The Gigmill pub will remain closed while police investigate the incident.
Detective Sergeant Paul Jeffs from Brierley Hill CID, said "This is a serious incident involving both a firearm and a vehicle and four people have been injured.
"We believe that this was a targeted attack and quick-time investigations are being carried out to establish the whereabouts of the driver of the Volvo.
"We would ask anyone who has any information or dashcam from around the time of the incident, and who has not already spoken with officers, to get in touch."
