Two young children were found alone in an Arlington apartment complex Thursday morning.
Police say a 4-year-old child was found wandering through the Carriage Hill apartment complex on the 1600-block of Jones Drive and was taken to the front office.
Police went to the child's apartment and found the girl's 2-year-old sister inside, alone.
The 4-year-old told police she was babysitting. Both of the children are OK.
Arlington Police said that the mother told them that the girls were left in the care of their teenage brother.
"[The mother] said she would come back during her break to take them to daycare," said Officer McDonnell.
Police believe the teenage son went to school, leaving the young girls behind. Police say they believe the girls were alone for about 90 minutes.
Child Protective Services took the girls from the apartment Thursday afternoon, but did not comment on the situation.
Arlington Police say they will not file charges and believe this was an isolated incident.
