MIAMI BEACH, Fla. -

About 250,000 people are in South Beach for Memorial Day weekend and the hip hop festival known as Urban Beach Week.

The festival is known for its over the top parties and fashions. Seventy-nine people were arrested Saturday, bringing the total number to 228. That's compared to 107 people arrested the same Saturday last year.

Police beefed-up presence in the wake of last year's police-involved shooting that left a man dead.

The Miami Herald reports the new efforts include watch towers, police in pairs on numerous street corners, closure of beachside Ocean Drive and a DUI checkpoint.

Authorities also deployed scanners on key causeways leading to Miami Beach to check license plates for stolen vehicles, outstanding warrants and the like.
