Waco police say a man and a woman have been arrested after leaving their 7-week-old daughter alone in a hotel room when they went to a grocery store to get a cigar product used to smoke marijuana.

Police believe that during the parents' absence of about 30 minutes Saturday, smoke from marijuana use set off the room's smoke alarm. Police say a housekeeper responding to the alarm found the infant and notified police.

Police say 29-year-old Nicholas Howlett was arrested for possession of marijuana and abandoning a child, and 19-year-old Leah Omollo was arrested for abandoning a child. Both remained jailed Sunday. Howlett's bond was $26,000, while Omollo's was $25,000. Jail records didn't list an attorney for either.

Police say Child Protective Services placed the infant with family members.
