TUCSON, Ariz. (13 News) - Several 13 News viewers reached out about loud noises they heard in Three Points Saturday, Oct. 11.

On Monday, Pima County Sheriff Chris Nanos confirmed that it was his bomb team disposing of some blasting caps.

Nanos said that an older man found the blasting caps and brought them to the PCSD’s substation on West Ajo Highway.

He said that the bomb squad decided the safest way to dispose of the caps was to detonate them immediately in a “controlled environment” behind the station.

The Sheriff said if anyone comes across anything like this, they should not touch or move it and call PCSD or 911.
