Pool quality probed as swimmers fall ill

NEW DELHI - Commonwealth Games organizers launched an investigation into the water quality at the troubled event's pool on Thursday after reports that over 50 swimmers had fallen ill.

Around 40 English competitors and 12 Australians had complained of feeling unwell after competing at the S.P. Mukherjee Aquatics Complex, with team officials insisting that the problem area was the warm-up pool.

"We must investigate this immediately. If the water is unsafe then clearly you can't swim in it," said Commonwealth Games Federation president Mike Fennell.
