Doctor worked despite NHS ban.
Dr Kumar Kisor Pal misled Durham Constabulary and a GP out-of-hours service, the General Medical Council was told.
The GMC heard Pal worked for both for a month until they were tipped off about the ban by health chiefs.
He is the second GP this year to face a disciplinary panel for moonlighting for Durham Police. Nabil Awadalla Naroz was struck off for working for the force while on the sick.
Pal had been suspended by South Tyneside Primary Care Trust on February 17 2005 for an "undisclosed matter".
The order meant Pal was banned from working as a GP, the hearing was told.
But he continued to work as a police surgeon and for the GP service Primecare.
Pal also did a forensic medical examiners' course while he was suspended.
Pal claimed the NHS ban had not made it clear what work he was allowed to carry out. But Lydia Barnfather, for the GMC, said: "What Dr Pal did was mislead his employers about his employment status with the PCT and was thereby dishonest."
The hearing continues.
