PEARLAND, Texas -

A woman on the run from police is behind bars after posting a boastful tweet.

Police arrested Mahogany Mason-Kelly, 20, at Lamar University on campus Friday.

Earlier in the week, Mason-Kelly posted, "I still got a warrant in Pearland...Those pigs will never catch me!!!NEVER!"

Further investigation and fingerprint comparisons found that Mason-Kelly had falsely identified herself as her sister Turquoise during a traffic stop on May 17, 2011.

On that day, Mason-Kelly had been stopped for a traffic violation and issued a citation in her sister Turquoise's name.

A computer check found that Turquoise Mason-Kelly had an outstanding warrant for her arrest with the Houston Police Department.

Mason-Kelly was arrested for the outstanding warrant and was booked into jail in her sister Turquoise's name.

Mason-Kelly signed the name Turquoise to all documents and, throughout her incarceration, continued to pass herself off as her sister, according to police.

Mason-Kelly admitted to providing officers with her sister's identifying information when she was arrested.

Houston police records also include a mug shot of Mason-Kelly in jailed that is listed as her sister.

Mason-Kelly is facing misdemeanor charges of tampering with a government record and giving police a false name.

Mason-Kelly was out on bond Friday April, 21.
