There's a new acting police commissioner in Yonkers.

Mayor Mike Spano nominated 27-year veteran of the force, Christopher Sapienza.  

He succeeds Commissioner John Mueller, a 28-year veteran of the force.

The Yonkers Police Department held a walkout ceremony for the outgoing commissioner earlier in the day.

Sapienza will serve as acting commissioner until his position is confirmed by the Yonkers City Council.
