(Corrects first paragraph to attribute allegation of mismanagement and misappropriation to the regulator)

TORONTO, May 12 (Reuters) - Ontario Securities Commission on Wednesday extended the suspension of trading in securities held in lender Bridging Finance Inc.'s funds after the regulator said last month that it had uncovered evidence of mismanagement and misappropriation of investment funds by BFI and certain members of its senior management team.

The Ontario Securities Commission, which on April 30 ordered all trading in the securities cease for 15 days, extended that timeframe to Aug. 12. Some of these securities are traded on online fund distribution network Fundserv.

The OSC said on Friday that PriceWaterhouseCoopers, which had been appointed as receivers for Bridging Finance, had terminated Chief Executive David Sharpe. (Reporting By Nichola Saminather Editing by Bernadette Baum)
