Police were investigating a homicide at a construction site in Walnut Creek and had a man in custody Thursday night, according to the police department.
At about 7 p.m., officers responded to reports of a disturbance and possible assault at a construction site in the 1800 block of Lacassie Ave., police said. When they arrived, they found a 60-year-old man with life-threatening injuries.
Officers and medical personnel provided life-saving measures, but the man was pronounced dead at the scene, police said.
Hakim Madjour, 34, was detained at the scene, police said.
It is believed Madjour and the victim knew each other and were both working as security guards at the construction site, police say.
Evidence indicated the suspect attacked the victim with a large metal pole that was recovered from the scene.
Madjour was ultimately to the Martinez Detention Facility where he was booked and is currently being held on $1 million bail.
