Bangkok police chief Lt Gen Siwara Rangsiphrammanakun says that Montri Sotangkur, a senior palace official under former Princess Srirasmi, faces up to 20 years in prison from four arrest warrants.
He said today that the official was accused of abuse of authority by claiming royal connections in demanding positions with two of Thailand's influential private enterprises.
Several family members of former Princess Srirasmi were detained in a high-profile corruption scandal late last year, shortly before she relinquished her royal title.
