Two Palo Alto men were walking on Colorado Avenue Monday night when they were attacked by four large men who demanded money, according to Palo Alto police.
"They punched him and knocked him down to the ground and kicked him," Agent Dan Ryan said Tuesday.
The victims, 30 and 43 years old, suffered only minor injuries, Ryan said.
The incident began around 10:25 p.m. when the two men were walking east on Colorado Avenue near Ross Road.
The four men were heading toward Middlefield Road and crossed the street to approach and try to rob the victims, Ryan said.
"I think they were just out cruising around so they parked and came up to them," Ryan said.
Neither Palo Alto man had any money and one of the victims tried to escape at the urging of his friend, Ryan said.
The suspects — all black males, over 6 feet tall, heavyset, wearing hooded sweatshirts and dark pants — fled in a white Buick-like sedan with "55" as the last two numbers of the license plate, police said.
Ryan said they have no suspects.
Anyone with information is asked to call the detective division at 650-329-2406.
