GLENDALE, Ariz. -- A former Glendale assistant police chief said he's appealing his demotion and suspension.
Greg Dominguez was demoted to commander and given a 40-hour suspension for violating policy earlier this year.
Dominguez told Phoenix TV station KPHO that his teenage son has struggled with addiction to the synthetic marijuana product known as "spice."
The 27-year police veteran said he twice went to a Peoria smoke shop and threatened to kill the clerk and burn the place down if they didn't stop selling spice to his son.
The shop owner lodged a complaint with Glendale police and an internal investigation determined Dominguez violated department policy.
Interim Chief Debora Black demoted Dominguez.
City officials announced Tuesday that Black has been named the city's police chief. She had been interim chief since March 2012.
