Officials were blocked from entering the temple grounds earlier in the week.
The bears were discovered Wednesday (April 1) when wildlife officers visited the temple to investigate a report of three missing tigers.
Officials said the temple was not authorised to have Asian black bears, which are a protected species.
Hornbill birds and Siamese fireback pheasant were previously confiscated from the temple located 180 kilometres northwest of Bangkok.
Officials said they would continue to investigate the report of missing tigers.
