NEW CANEY, Texas -

A man has been accused of threatening to detonate a bomb at a Montgomery County building.

Montgomery County sheriff's deputies said Troy Don Tindall, 20, called them about 11 p.m. Wednesday and said he put a bomb under Montgomery County Precinct 4 Constable's Office patrol car at the East Montgomery County Annex in New Caney and was about to set it off.

Tindall gave the call taker his name and claimed that the bomb was chemical-based and contained shrapnel.

The annex building, which contains a holding facility for inmates waiting to be transferred to the county jail, was evacuated while investigators searched for the alleged bomb.

Deputies later found Tindall walking on a road near the annex. He ran away at first and shouted to deputies that he had outstanding warrants, investigators said.

Tindall was captured a short time later and admitted to making the bomb threat, detectives said.

Tindall was charged with false alarm or report of emergency and evading arrest.
