Owners of a frozen yogurt firm who are suing Loblaw for $20-million accused the big Canadian grocery giant Tuesday of “deliberately” using a power drill to damage its company computer files.

YoPRO co-founder Amanda House posted a second YouTube video claiming Loblaw sabotaged a computer hard drive with a drill to destroy their sensitive partnership e-mails.

In an interview with the Toronto Sun — and in an online video — House accused Loblaw Cos. Ltd. executive chairman Galen Weston Jr. of failing to act on her complaints following an hour-long meeting Dec. 14.
