An underage drinking investigation leads to an arrest at a Port Jefferson bar.

Suffolk police say they raided the Portside Bar and Grill on East Main Street in response to community complaints.

They arrested Christopher Chernis, 34, and charged him with unlawfully dealing with a child.

The bar's owners were also given several violations by the State Liquor Authority.

New York state announced Friday that it would be cracking down on underage drinking and fake IDs.

The SLA is planning visits to 500 stores and restaurants to conduct checks.
