In June 1986 Mehmet and Ali start a cab firm called 'OzCabs' from a corner table in Ali's Café. Mehmet is married with three children, but monogamy is one sanctity of marriage that he is more than willing to overlook. Later that month punk Mary Smith (Linda Davidson) catches his eye, and so he bets his sceptical brother £10 that he can get Mary to have sex with him. Mary is well aware that Mehmet's intentions are dishonourable and initially refuses to have sex with him, but Mehmet persists and she finally relents and spends the night with him. A triumphant Mehmet then collects his winnings and gloats to his brother in the café. However, Mary overhears their entire conversation and she then sets about trying to get revenge on him by hoax calling his cab-firm and vandalising his car. Later in the year Mehmet acts as Pat Wicks's (Pam St. Clement) pimp, setting her up with clients on a regular basis and he even persuades Pat to convince Mary to go prostitute herself too. He also gets involved in Kathy Beale's (Gillian Taylforth) Knitting business, later conning her and disappearing with all her profits. After he gets into more trouble with his customers for overcharging on fares and then trying to seduce Hannah Carpenter (Sally Sagoe) — the wife of his employee — the residents of Albert Square decide to confront him. Den Watts (Leslie Grantham), Pete Beale (Peter Dean) and Tony Carpenter (Oscar James) find him and give him a severe beating which involves having his arms pinned behind his back whilst taking a number of blows to the stomach.
