Officers amplified security at Caltrain's Redwood City station Saturday (March 5) after about a dozen assailants attacked a man at the station on Friday, a spokeswoman said.
Between nine and 15 suspects attacked a 47-year-old San Jose man in an attempt to rob him at about 7:30 p.m., spokeswoman Christine Dunn.
The man, who was waiting for a southbound train, was beaten and left on the ground after the attack. No weapons were seen during the scuffle, Dunn said.
The victim was taken to a hospital and was listed in critical condition. He was still in critical condition as of 6:20 p.m. Saturday evening, Dunn said.
Given the severity of the mauling, investigators from Caltrain police are now "aggressively" following leads into the possible whereabouts of the suspects, including reports of a white compact car seen leaving the station, Dunn said.
She said she was not able to discuss the nature of the victim's injuries or details of the investigation, but said police are asking for the public's help in the case.
Anyone with information about the attack is encouraged to call Detective Victor Lopez at (650) 622-8048.
