Police chief Eddie Hui Ki-on presented a top-of-the-class award to his eldest son at an auxiliary police graduation ceremony yesterday but said he would not encourage him to join the regular force. Hui Wing-fai, 29, is an accountant by profession but decided to join the auxiliary police six months ago without first telling the Police Commissioner. 'He didn't tell me about it until after he had joined,' Mr Hui Snr said. 'But it's a good thing he did - good training for him. ' But his son should not switch to the regular force because 'at his age, it's a bit late; he would never reach my post, and he already has a profession.' Some 160 constables graduated yesterday at the Auxiliary Police Headquarters in Kowloon Bay. Mr Hui Jnr has been posted to Central and is expected to take up duties next month. He declined to be interviewed. Meanwhile, the commissioner said the police would check on officers working outdoors following the Chief Secretary Anson Chan Fang On-sang's order that all government departments had to improve their monitoring of staff.
