Bortoleto and Hülkenberg under investigation after US GP practice incidents

Gabriel Bortoleto came under investigation after apparently impeding Lewis Hamilton at Turn 12 in final practice for the United States Grand Prix at the Circuit of the Americas. Hamilton was on a fast lap and had to brake hard as Bortoleto travelled slowly on the racing line.

Nico Hülkenberg was also under investigation, over an alleged breach during a practice start at 12:41 local time, 11 minutes into the session. Hülkenberg was due to face the stewards first, with Bortoleto to follow shortly after.

Hamilton went on to top the FP3 timesheet for the first time in two years.
