Two brothers of Kings Cross identity John Ibrahim, Michael Ibrahim and Fadi Ibrahim, have been arrested in Dubai as police smash an alleged long-running organised crime syndicate.

The pair are among 14 people arrested, including John's son, Daniel Ibrahim, and underworld figures Mustapha Dib, who was also arrested in Dubai, and Rock Ahmad, who was taken into custody at his Bankstown home.

The arrests relate to long-running syndicates that have been allegedly smuggling drugs and tobacco into Sydney for decades.

More than 25 homes are also being raided, including the Dover Heights house belonging to John Ibrahim.
