Two men have been arrested in Devon on suspicion of publishing racially inflammatory material on the internet.
Police arrested the men, aged 65 and 41, at addresses in Cecil Road and Redlands Court in Paignton.
A quantity of material was seized by officers investigating the posting of inflammatory material, Devon and Cornwall Police said.
Detectives said the operation followed "a number of incidents" which had been brought to the attention of police.
A force spokesman added: "We have yet to analyse what has been seized but we will then be in a better position to look at what, if any, offences have been committed."
Both men were later given police bail until 31 May.
