German side VFL Bochum are investigating claims of racial abuse aimed at Arsenal loanee Jordi Osei-Tutu.
The 20-year-old was subject of an incident in his first game for the club since joining last month, a friendly against Swiss side St Gallen on Tuesday night.
He reposted a video of the incident, showing him visibly upset while his team-mates tried to defuse the situation, on his Instagram feed with the caption "Say No To Racism".
"I am very disappointed about what happened," said Osei-Tutu.
"No one should ever be subject to any discrimination and it is really hard to understand how a fellow professional footballer could do this.
"Arsenal and Bochum have provided great support to me and I hope that if nothing else, we can show that racism has no place within football."
In another social media post, Bochum have announced they will be looking into the incident and reassured fans that they will be supporting their player.

Arsenal also released a statement on Wednesday saying they are "working closely with Bochum and Jordi and we are giving him our full support.
"Racism has no place in our game and we do not tolerate any form of discrimination."
Osei-Tutu stepped up to Arsenal's U23s in 2018 and made 18 appearances to help win the title, but is yet to debut with the senior team.
In April, the Arsenal player participated in the PFA's "Enough" campaign making a stand against racism and abuse in football.
Bochum, who are based just outside of Dortmund, play in 2. Bundesliga and finished last season in 11th place.
