The man was arrested on Monday night and was charged with stalking, using telecommunications device to menace, making threat to commit sexual offence and other charges.
Grimes had brought the vile comments to the attention of the police after feeling concerned for the health of his family.
Grimes brought the comments to attention on Instagram after receiving them on social media.
The Police released a statement for a Frankston man that is to appear in the Magistrates Court in May next year.
“Police executed a warrant at a Frankston address on Monday 24 August as part of an investigation into alleged online harassment,” the statement said.
“Detectives arrested a 39-year-old man and charged him with stalking, using telecommunications device to menace, making threat to commit sexual offence and other charges.
“He was bailed to appear before Frankston Magistrates’ Court on 4 May 2021.”
Grimes said the comments warranted the police’s attention.
“The severity and pointed nature of these threats went way beyond what I would call normal post-game banter with this individual, so much so that we were concerned for the safety of my family back home in Victoria,” Grimes said.
“Honestly, I am disappointed that this has escalated to this extent. I’d really like to move on from it and get back to focusing on footy, but at the same time I also encourage people to continue to call out this kind behaviour. It’s not right for anyone, including players and their families, to have their safety threatened.”
Richmond CEO Brendon Gale supported Grimes’ stand.
“No one should have to tolerate this, and as an AFL industry, we need to continue to unite, educate, call out and stamp out this ugly, abusive behaviour,” Gale said.
“Dylan has taken an important stand on an issue that is simply unacceptable.”
