HUDSON, N.H. -- Three men, including one from Massachusetts, were arrested by Hudson police conducting an Internet sex sting.

The men thought they were having online chats with underage juveniles when in fact they were communicating with a Hudson police detective, police said.

All three then traveled to Hudson to have sex, police said, where they were met by detectives. The police ran the sting on three successive days starting Thursday.

Anthony Christopher Blondin, 21, of Salem, N.H., Kenneth Lawrence, 51, of Manchester, N.H., and Anthony Van-Dyck, 32, of Burlington, Mass., were all charged with computer crimes.
