The home side shaded the first half with Rodoljub Paunovic coming close on three occasions. His first attempt was scooped over the bar on three minutes while his second was a low shot saved by Pattara. The Serb's third effort of the half curled inches wide after he'd been set up by Bas Savage.
Police never really had any clear cut chances in the opening period, but it was them who took the lead in the 52nd minute when Lee Han Guk sent a rasping shot past Manthewa.
On the hour, Noppol's curling free kick from the left clipped the crossbar as TOT pressed for an equaliser.
With 15 minutes left, Police played their defensive card by taking off Daniel Cortes, who'd looked their best attacking threat, to bring on Whoo Hyun as a defensive midfielder.
That tactical decision backfired three minutes later when Panomkorn drilled a low shot home to level for the hosts.
Pokkhao almost restored the lead for Police after his shot was tipped onto bar and over by Manthawa.
As the clock whittled down, TOT made a defensive change and both managers seemed content with a point. The draw meant the duo remain unbeaten and moved onto four points.
From what I saw, both sides have mid-table written all over them and I'd be surprised if either of them got sucked into a relegation battle.
