Federal prosecutors say a northern New Jersey mayor and his adult son hacked into political opponents' computers.

West New York Mayor Felix Roque and his 22-year-old son, Joseph, each face more than 10 years in prison if convicted on charges of gaining unauthorized access to computers, conspiracy and causing damage to protected computers.

Both were arrested Thursday morning by FBI agents.

Bail for both men was set at $100,000 during an afternoon court hearing, and they were ordered to surrender their passports. They also may only travel between New York and New Jersey, and cannot contact the alleged victims or possible witnesses.

A preliminary hearing was set for June 4.

Roque is a Democrat who beat former Mayor Sal Vega in the city's nonpartisan election on May 10.
