Police have described the shooting of a paramedic with an air rifle or BB gun as he treated an injured man as 'truly shocking'.
Officers are hunting for the culprit who fired several plastic pellets at paramedic Allan Norman at lunchtime on Wednesday.
Mr Norman was hit on the motorbike helmet he was wearing, and other shots were fired at him and colleagues.
He had been called to Watts Road, Buckland, Portsmouth, at 11.53am to treat a man who had fallen from a lorry. The attack happened at 12.20pm.
PC Steve Webber said: 'We are appealing for anyone who may have witnessed this incident or who knows who may have shot the pellets to come forward. Thankfully no one was injured. However, this could have been a much more serious incident and to target the emergency services whilst they are treating an injured person is truly shocking.'
Mr Norman, who has been a paramedic for 24 years, branded the attack as unforgivable and senseless.
Anyone with any information regarding this incident should contact PC Webber at Fratton police station on 0845 045 45 45 or call Crimestoppers, anonymously, on 0800 555 111.
