Travis County jail records show 17-year-old Erik Marciel was being held Thursday on two counts of attempted burglary of a habitation.
Online jail records don't list an attorney for Marciel, who was booked Wednesday with bond set at $7,500. He is being charged as an adult.
Austin police say a 10-year-old and a 13-year-old have also been detained. Police declined to name the boys.
Investigators say another suspect is being sought after reports of house break-ins on April 10. Police responded to reports of a neighbor seeing four people acting suspiciously near a home, including trying to open the windows.
