Storylines[]
Police Constable Myra Sim is a police officer who investigates Wellard's kidnapping. She speaks to Mickey Miller and Gus Smith, and finds the recently departed Li Chong's stash of dodgy mobile phones. Mickey asks her not to tell Gus about the phones, which she does not. When Bert Atkinson later plasters posters of Wellard around Walford, she deals with a complaint about them, telling Gus to take them down or he will be fined. She appears again on 26 December 2009 and 28 December 2009 following the murder of Archie Mitchell, questioning Bradley Branning and Stacey Slater. She is also present at the police station and takes Ronnie Mitchell's clothes from her for forensic analysis after she is arrested for the murder.
