A 36-year-old man and three teenagers were arrested over the weekend in connection with last week's string of acid bomb explosions near local restaurants.
Clearwater police said the adult suspect, Brad Saari of Clearwater, helped the three minors manufacture the explosive devices and accompanied them as they detonated two of the small homemade bombs in Clearwater Beach.
In addition to felony charges of making and detonating a destructive device, Saari, who was watching one of the boys while his mother was away on business, was also charged with child abuse.
Because of the abuse charge, the minors, a 14-year-old from Clearwater, a 15-year-old from Belleair and a 16-year-old from Largo, are not being named by the St. Petersburg Times.
Clearwater police spokeswoman Elizabeth Watts said the suspects were identified after tips came in from area residents after video surveillance tapes were released to local media.
Saari, who was booked into the Pinellas County Jail Friday with his last name spelled "Sarri," is being held on $65,000 bond.
