A man arrested in Rothwell earlier this week has been released on police bail.
The man, who has not been named by police, was taken into custody on Tuesday, January 6.
Northamptonshire Police had received reports from the town to say a man was acting suspiciously.
But a police spokesman stressed at the time that the man was arrested in connection with a different incident.
However, officers also visited schools to provide reassurance to staff and pupils.
