Police officials in Lehighton and Mahoning Township will confer with District Attorney George Kerestes following the questioning of 18 Lehighton area teenagers on charges of molesting and "bushwacking" couples in parked cars in Mahoning, the alleged violation having occurred near the Orioles Club headquarters. The police inquiry came after two Lehighton youths, ages 14 and 17, were injured by fragments of metal from a homemade explosive tossed from a parked car. Identity of the 22-year-old Lehighton man, responsible for throwing the cylinder "to scare off the youths" is being withheld.
