The state Attorney General's office and local law enforcement launched an investigation this week focusing on Internet cafes, including one in Oceanside, that allegedly offered illegal gambling.

As part of the investigation, Oceanside police served a warrant on Lucky Bob's Internet Cafe on Mission Avenue, a spokesman for the department said Friday morning.

On Wednesday, investigators conducted multiple inspections at Internet cafes and small businesses with slot machines and computer gaming devices, including five in San Diego, according to the San Diego Police Department.

Police arrested two people, confiscated 31 gaming devices and seized more than $11,000, San Diego Lt. Rudy Tai said.
