A BRITISH Transport Police officer was justified in using an incapacitant spray against fighting Celtic and Ajax fans, an independent investigation has ruled.

The spray was used by one of two officers as they dealt with an outbreak of violence among more than 15 rival supporters following a Champions League match in Glasgow on October 22.

The case was referred by BTP to Professor John McNeill, the Police Investigations and Review Commissioner, who said the officers had managed the incident professionally. However, he recommended procedures for using Captor Incapacitant Spray are updated to ensure officers have "clear instruction and guidance" on using the device in areas outside railway stations.

Professor McNeill said: "I am satisfied that the officers managed the incident professionally."
