The attack and robbery happened just after 5 a.m. Friday near the Rose Bowl on West Drive, north of Salvia Canyon Road, said Pasadena police Lt. Terysa Rojas.
"Other pedestrians exercising in the area found the victim laying on the ground and called 911,'' Rojas said. "The victim sustained major head trauma and remains in critical but stable condition at a local hospital.''
The suspects took money and the man's identification and credit cards, Rojas said.
"Shortly after the robbery, the four suspects were recorded on video at a Pasadena service station attempting to use the victim's credit card,'' she said.
All of the suspects - three males and a female -- are described as Hispanic.
One of the males appears to be in his 20s, with a medium build, dark-colored hair and beard and was wearing a white T-shirt, light-colored shorts and tennis shoes.
Another is believed to be in his teens to early 20s. He has a thin build, short black hair and was wearing a dark hooded sweater with a circular design on the front, light-colored shorts and black and white tennis shoes.
The third male is believed to be in his 20s. He has a stocky build, thick eyebrows and was wearing a white T-shirt and dark-colored pants.
The female is thought to be in her teens. She has long brown hair and was wearing a dark hooded sweatshirt with white lettering on the fromt.
All four were seen in a black 2003-2004 Honda Accord coupe with a sunroof.
