Singapore: The sex-for-grades corruption trial against law professor Tey Tsun Hang was adjourned, after he suddenly slumped over while in the dock.

The hearing had just resumed after lunch.

Lawyer Peter Low, who is advising Tey as he conducted his own defence, told the court that his client was "hyperventilating".

Chief District Judge Tan Siong Thye allowed a brief adjournment until 3.30pm.
