A doctor says the condition of a 5-year-old girl who was allegedly kidnapped, raped and tortured by a man and then left alone for two days in a locked room in India's capital has improved.

D. K. Sharma said Sunday that the girl was responding well to treatment and that her condition was stable.

Police say the girl went missing April 15 and was found two days later by neighbors who heard her crying in a room in the same New Delhi building where she lives with her family.

A 24-year-old man has been arrested in connection with the incident.

For the second consecutive day, hundreds of people protested Sunday outside police headquarters, angry over allegations that police had ignored complaints by the girl's parents that she was missing.
