Plymouth have confirmed that a man was arrested on suspicion of racially aggravated harassment during the npower League Two clash with Southend on Saturday.
Devon and Cornwall Police detained a 33-year-old man for the alleged offence but he has since been released on bail pending further enquiries.
The Pilgrims on Tuesday released a statement regarding the incident, which read: "We are grateful to supporters who have raised concerns about racist language heard at our recent npower League Two game against Southend United, and we can confirm that one person was arrested for alleged racial abuse.
"An immediate enquiry was launched by club officials on learning of the impending arrest at half-time of the game. This arrest confirms a very simple unequivocal message embraced by everyone at Plymouth Argyle and connected with the club - racism has no place in football; no place at Home Park; no place in Plymouth.
"We operate a very clear policy of zero tolerance towards any form of unacceptable discrimination whether it is based upon race, creed, religion or sexual orientation. Any form of discrimination has never been, and never will be, tolerated at Home Park.
"We remind all supporters that racist, sexist and homophobic chanting are criminal offences which will result in the perpetrators being banned from Home Park."
