A coach carrying Chinese tourists pulled up near to Grenfell Tower so the group could take pictures of the charred building, it has been claimed.
The visitors were accused of engaging in "disaster tourism" by taking snaps of the wreck, The Times reported.
The tour guide has allegedly been sent back to China and a coach driver suspended after the alleged unscheduled stop in west London.
Passers-by were supposedly told the tourists were health and safety experts.
James Buckingham, operations director at BM Coaches, told the Times: "I would like to apologise most sincerely on behalf of BM Coaches for the insensitive actions of the group we were contracted to supply transportation to,"
The company also made a donation to the Grenfell Fund as an apology following the incident on Wednesday, the paper reported.
Up to 80 people died in the tragedy on June 14, where fire engulfed the 24-storey building within minutes.
