DIGHTON, Kan. (KSNW) – The City of Dighton said the swimming pool reopened Tuesday after it had to be drained and swept.

The sheriff’s office says someone broke several beer bottles during an after-hours party late last week. The damage was discovered when lifeguards and the pool manager arrived Saturday morning.

The pool was drained, swept and refilled within just days.

The City of Dighton is offering a $500 reward for information leading to the arrest and conviction of the person or people who trespassed and vandalized the pool.
