Hutchinson police responding to a suspicious activity call arrested a pair for having sex in an illegally parked truck in a central Hutchinson alley Sunday afternoon.

The 38-year-old woman and 44-year-old man were arrested on suspicion of lewd and lascivious behavior, having intercourse in the presence of someone over age 15.

Police also booked the woman on possession of marijuana, methamphetamine and hydrocodone, for suspected drugs found in her purse, failure to appear in five different cases and interference with a law enforcement officer for giving a false name.

When police arrived in the alley in the 900 block of North Ford about 3:30 p.m. at least one of the suspects was found with no clothes on and the two engaged in intercourse, police said.
