Food chain Nando's has denied using the murder trial of paralympian Oscar Pistorius in its marketing material.
"Our attention has been drawn to fake Nando's ads doing the rounds on the internet," it said in a statement on Friday.
"The visual identity used in these fake adverts bears a remarkable resemblance to that of Nando's and sometimes even uses the Nando's corporate identity."
It said the fake material had the potential to cause damage to the reputation of Nando's.
"As such, we do not endorse this unauthorised and irresponsible use of our brand."
This week, an advertisement that resembled the Nando's branding did its rounds on social media sites.
The advertisement had a picture of a burger with the words "The Michelle Burger extra grilled".
Burger was the first witness to testify in the athlete's murder trial, which began on Monday, and was subjected to extensive cross-examination.
