Canada’s border service agency is working out the kinks in its investigative techniques  while complaints against employees are left undetermined.

Out of 78 complaints about the Canada Border Services Agency made in the span of one month in 2014, 14 cases are classified as undetermined.

Undetermined complaints include accusations of an officer assaulting a person, allegedly leaving deep scratch marks on their arm.

“Endured hours of detainment, hand-cuffed, strip-searched, horrific harassment by CBSA armed and loaded officers,” reads another undetermined complaint.

A 2015 internal audit revealed the weaknesses in the agency’s investigative techniques.
