Dallas Fire-Rescue's swift water team has been called to assist a person in danger Tuesday afternoon.
The call came in at about noon and may be related to the missing persons report filed for Dallas Assistant Police Chief Gregory Holliday, who was last seen at about 2 p.m. Monday.
DFR emergency responders were called to a wooded area near White Rock Creek, not far from the 4900 block of Haverwood Lane. The location is south of the President George Bush Turnpike and east of the Dallas North Tollway.
Dallas Police Department's Mounted Patrol is assisting in the search.
Just before 1 p.m., the mounted patrol tweeted the following:
