The gymnast – who won silver at the Rio Olympics for the pommel horse – missed the “Heroes Return” and a Buckingham Palace reception to apologise to the Muslim community over an “offensive” video.
Louis met with Muslims in London at Fazl Mosque in Southfields and Baitul Futuh Mosque in Morden while the Britain”s Olympians and Paralympians met thousands of fans in Trafalgar Square yesterday.
Speaking about the visits Louis in a Facebook post said: “I was a little nervous and anxious before visiting [the mosques] because of the events in the last week.
The former Strictly winner added: “[During the visits] we discussed my actions and they showed me what they learn and the true meaning behind their religion of peace.
“The community work they do for various charities is actually crazy and the money raised each year would blow your mind.”
Trying to make amends Louis also missed the Buckingham Palace reception, hosted by the Queen and Duke of Edinburgh, after the parade for Rio medallists.
The Olympian is now being investigated by British Gymnastics and could face suspension.
Farooq Aftab, national vice president of the Ahmadiyya Muslim Youth Association said: “The original video that gave rise to this whole incident has caused offence.
“Louis did something wrong but he certainly does not need to be defined by that brief moment in his life.
“His apology and visit to London”s oldest mosque and western Europe”s largest today to learn about Islam speak volumes.”
