TOPEKA, Kan. (AP) — Authorities are looking for a Topeka woman and say her estranged husband took her against her will.

Topeka police Lt. Chris Heaven said Thursday morning that officials are “very concerned.” The Topeka Capital-Journal reports that an arrest warrant has been obtained for 38-year-old Pedro Enrique, whose 33-year-old wife, Viviana Vazquez, filed for divorce in April.

Police say her kidnapping was reported around 7 a.m. Wednesday. Authorities say two children were left behind and weren’t injured. Divorce records show that the couple had 3- and 10-year-old children.

Later Wednesday, officers thought they saw movement while preparing to serve a search warrant at Enrique’s house. But police determined the house was unoccupied after efforts were made to make contact with anyone inside.

Police continue looking for a silver Chrysler PT Cruiser.
