Fresh vision has emerged of Minnesota ICU nurse Alex Pretti clashing with US border patrol agents almost a fortnight before he was shot dead by federal officers. Digital outlet The News Movement obtained previously unseen footage of Pretti, 37, becoming involved in a physical altercation with ICE officers in Minneapolis 11 days before Saturday's fatal shooting. A Border Patrol officer and a CBP officer each fired Glock pistols, the notice said. Pretti was fatally gunned down by federal agents on January 24. (Reuters)The two US immigration officers involved in the deadly shooting have been placed on leave, officials said.
