Of those, 150 took place on Saturday night, when England lost to France in the quarter-finals.
In total, 115 arrests have been made since the start of the tournament, a high proportion of which are linked to incidents at licenced premises.
By the same stage of the World Cup in Russia in 2018, 225 football-related arrests had been made in the UK.
Roberts said the restrictions on alcohol in Qatar helped with fans’ behaviour “to some degree”.
“The behaviour of England and Wales out in Qatar was absolutely exemplary,” he said.
“In Russia 2014 there were three arrests but, having two teams in this tournament, we played double the group stage games, including a home nations derby, which underlines the good nature of our fans.”
