A Gloucestershire Police spokesman said: “The reports have mostly involved clowns carrying knives.
“In one case a child was followed. Clearly this has scared people and caused real distress.
“We have attended these incidents as grade 1 emergencies and that limits our ability to attend to other incidents.
“We haven’t traced anyone involved as yet as they have disappeared by the time we arrive but anyone we do find will be dealt with appropriately.
“Whether those involved are doing it for a joke or not, this is no laughing matter.
“These are stupid acts that are really frightening people and wasting our time. Please don’t be tempted to do it. Think of the consequences.”
