Vandals over the weekend threw rocks through three large windows at the Tacoma Public Utilities Administration Building and damaged up to a dozen more.
Tacoma police were called to the building at 3628 S. 35th St. about 7:15 a.m. this morning and are investigating.
“A slingshot might have been involved,” said TPU spokeswoman Nora Doyle.
She said the three 7 foot by 10 foot windows with small holes located the on the west side of the building will be replaced at cost of $1,000 each. Two were on the first floor and one on the second floor.
The other windows on the north side of the building had nicks in them and no determination has been made on what to do with them, Doyle said.
