Another letter sent by the Monster with 21 Faces that was received on 23 April was sent to both Sankei and Mainichi newspapers as well as the Koshien police station.
The letter stated it had laced $21 million worth of the company's confections with potassium cyanide soda, and it later threatened to put them on store shelves.
None of these poisoned candies were found, but Glico products were removed from stores, resulting in a loss of more than $20 million and the laying off of 450 part-time workers.

In October 1984, a letter addressed to "Moms of the Nation" and signed by the Monster with 21 Faces was sent to Osaka news agencies with a warning similar to those sent to Glico.

[11] On 28 June 1984, two days after the Monster agreed to stop harassing Marudai Ham in exchange for 50 million yen, police came close to capturing the suspected mastermind.
In a later incident, investigators saw the Fox-eyed Man again, accompanying the alleged "Monster" group during another secret money exchange with House Food Corporation.
