Johannesburg - Shares of South African technology company Pinnacle Holdings claw back 4.8 percent to 12 rand after a two-day rout that wiped out 1.45 billion rand of the mid-cap's market value.

Investors have hammered Pinnacle after a company director was arrested for allegedly trying to bribe a senior police official.

The charges - together with filings that show Pinnacle's chief executive and executives sold stakes in the company before announcing the allegations - have also prompted a regulatory investigation. - Reuters
