A taxi driver was stabbed in what police are calling an unprovoked and "violent attack".
Wiltshire Police are looking for witnesses following the incident, which took place on 15 June in Dawlish Road in Swindon.
At around 5.30am the taxi driver picked up two men and one woman from a nightclub. As they approached Dawlish Road the passengers became abusive towards the driver.
Following an argument in the car, one of the men stabbed the driver before all three ran away towards Radstock Avenue.
The taxi driver suffered minor injuries and was released from hospital the same day.
Police officer Adrian Bray said: “This was an unprovoked attack on someone who was simply doing his job."
He added: "It could have been very different due to the violent nature of the attack."
Officers are continuing their investigations into the incident and have said they believe they know who the suspects are.
Wiltshire Police are looking for any witnesses who were in the Dawlish Road area of Swindon or who may have further information to contact them immediately on 101 quoting crime reference number 54190057409.
