The incident happened during a match between Cheltenham Town and Portsmouth at the Cheltenham Club's stadium yesterday.
"Although pitch invasion is an offence for which people can be charged, police consider this was an appropriate and proportionate response to a low level incident just prior to Christmas," police official was quoted by BBC News.
The dozen Father Christmas were fans of the respective clubs and had invaded to support their clubs, who were then ejected during half time from the stadium by match stewards.
Police described it as a "minor incident". The match finally ended in a 1-1 draw.
