Police from Hunter Valley Local Area Command are seeking public assistance to locate a man missing in dense bushland in the state’s Hunter Region.

Bob Baihn, aged 72, was last seen about 5.15pm on Sunday (16 May 2015) when he was searching for a missing pony on a property on Flaggs Road, Gungal.

When he failed to return to the farm house that afternoon, a search was initiated by his wife, with the assistance of a neighbour.

Mr Baihn was unable to be located prompting his family to contact police.

A full scale co-ordinated search was conducted utilising local police, Dog Squad, trail bikes, the Police Airwing, Police Rescue (LANDSAR) and SES volunteers.

The search was suspended overnight due to the rough terrain, but will resume about 8.30am today (Tuesday 19 May 2015).

Grave concerns are held for Mr Baihn due to a medical condition that requires regular medication.
