It took more than two hours for emergency crews to free a construction worker trapped in a concrete pipe in California. The incident occurred shortly before 9:30 a.m. on Nov. 8 when a construction worker was performing some type of work in an underground pipe. Emergency personnel were not clear as to how the man became stuck in the pipe, but the original call that came in was for a person trapped in a confined space near the area of Starlight Avenue and Oak Valley Parkway.
