A Lancaster Drive shooting involving rival juvenile groups injured one teen Saturday night, Alexandria police report. 

Lancaster runs north from Jackson Street to Castle Road. 

Investigators said, contrary to initial media reports, that no establishments on Jackson or in MacArthur Village were involved or threatened and the gunfire was not a random act. 

The issue at the heart of the dispute was not revealed, if detectives had yet nailed it down. 

Proceedings involving juveniles are confidential, whether they involve violence or otherwise. 

Agencies are limited to what they can release relative to underage suspects.
