A Bronx couple was indicted Thursday on child endangerment charges for leaving their 5-year-old son alone in a filthy apartment.

48-year-old Charlotte Lewis and 59-year-old Wilfred Lewis were arraigned in Bronx Supreme Court.

Last month, police were called to the couple's Kingsbridge Avenue apartment where they found the 5-year-old boy alone with insects on his body.

Police say the apartment was infested with rodents and the walls were stained with blood and feces.

The couple is due back in court in May.

They are being held on $15,000 bail.
