Original story: 5 a.m. April 22:
Elmhurst police swarmed a home on the 900 block of Fern after they received a call for "shots fired" at 7:30 p.m. Sunday, April 21.
"As officers arrived, they heard the rapid fire of BB/pellet guns," Police Chief Michael Ruth said Sunday night via email. "Subsequent investigation revealed that three adults and one juvenile were discharging BB/pellet guns in the rear of 959 Fern."
A witness at the scene said three offenders were on the ground in handcuffs and "at least nine squad cars" responded, including a unit from Berkeley.
The suspects were charged with disorderly conduct, Ruth said. They were released on bond. Information released on Sunday night is preliminary, Ruth said.
