Livermore police on Thursday announced arrests have been made in connection to a robbery and severe beating earlier this month.
The teen suspects were arrested on suspicion of robbery. One of the teens was also arrested on suspicion of attempted murder.
Their identities have not been released because of their ages.
On June 14, officers responded around 3 a.m. to an assault on a jogging path under the Stanley Boulevard Bridge at the corner of Murrieta and Stanley boulevards, according to the Livermore Police Department.
Police said several witnesses called to report a group of males beating another man with sticks and pipes.
Officers found the victim on the ground suffering from severe body and facial injuries.
Police said the victim was transported to the hospital, where he was admitted to the intensive care unit and underwent several surgeries.
On June 19, police, investigating the assault as an attempted homicide, arrested four juvenile males, ages 16 to 17, and an 18-year-old man, later identified as Michael Watson, in connection with the beating.
Police said detectives were also able to link the suspects to a robbery that occurred several hours prior to the assault.
Police said all but two of the suspects were eventually released due to lack of evidence.
The victim is recovering from his injuries.
The Livermore Police Department is asking anyone with information about the assault to call 925-371-4755.
