NEW YORK -- Police Thursday are investigating reports of two separate sexual assaults in Queens.

One assault was reported in Springfield Gardens and another in South Ozone Park. Details of the attacks are not immediately available.

The incidents comes a day after police said they were searching southeast Queens with bloodhounds for a man suspected of sexually assaulting a teenage girl behind an abandoned church. It is too early to tell if the three incidents are linked.

Police said the man grabbed the 16-year-old victim while she was on her way to school Wednesday morning. The man, who was armed with a box-cutter, made threatening statements and forced her to the rear of an abandoned church in Springfield Gardens where he forced her to perform a sexual act.

Police arrived on the scene after receiving a 911 call about a man and woman breaking into a church on Merill Street around 8:45 a.m. The suspect fled the scene when police arrived. The woman said she was being raped, according to police.

A police source says that this suspect may be the same man linked to as many as six sexual assaults at knife point earlier this year in southeast Queens.

Police are searching for a black man with the letter "D" tatooed to his right arm. Anyone with information about the suspect or his whereabouts is asked to call crimestoppers at 1-800-577-TIPS.
