After four years, leadership of the Robstown Police Department has changed hands.

City secretary Paula Wakefield said Friday that Johnny Brown, 51, a former patrolman who has been with the department for about 20 years, has replaced outgoing police chief Carlos Pena, also 51. Pena has been with the department for 27 years.

"He'll remain with the department," Brown said Friday, adding Pena's new position had yet to be determined.

No reason was given for Pena's demotion, but Brown said morale in the department has been down, and addressing that issue is going to be his primary focus.

"Just to kind of get the morale up, stop some of the crime that's been going on, burglaries and narcotics, and boost the morale in each division of the department," he said.

Brown said he's grateful to be given the opportunity to lead the police department and assist the community in feeling safe.

"I'm really excited," Brown said. "It's been a long time coming. Hopefully I can provide the best service that the citizens need."
