Yes, Sir, Mr. Mason was arrested by the Japanese police at Hsinking on 29th June during a disturbance. He was detained until 2nd July, and during the period of detention he appears to have suffered severe treatment and to have been refused permission to communicate with His Majesty's Consul-General at Mukden. Representations have been made to the Japanese authorities in Manchuria by His Majesty's Consul-General, and His Majesty's Ambassador at Tokyo has taken the matter up with the Japanese Government.
