A teenager from Scottsdale, Arizona has been arrested for allegedly raping two women, including a neighbor who lives in his apartment building.
DNA evidence linked the 16-year-old boy to the assaults, which happened one week apart on Oct. 18 and Oct. 24, police said.
The boy's name has not been released because he is a juvenile and it has not yet been determined whether he will be tried as an adult.
He is being held on sexual assault, kidnapping and burglary charges, and police believe he may be connected to more crimes in the area, according to a local Arizona television station, KPHO CBS 5.
Police were led to the suspect through a tip from the Scottsdale community, according to Sgt. Mark Clark of the Scottsdale police department.
The suspect's DNA was already in the police agency's database because he has a criminal past that includes crimes related to the ones he is currently being held for.
Authorities did not provide any further details on the boy's former crimes.
They said DNA testing is ongoing, as police collected additional samples from the suspect's home through a search warrant.
DNA samples that were on file have already been linked to both assaults.
The victims of the rapes could not identify the boy in a line-up of suspects, but police say there are some similarities between his appearance and a composite sketch of the suspect that was drawn with the help of the first victim's description of her attacker.
In both attacks, the assailant entered first-floor apartments through unlocked patio doors of women who live alone.
