‘EastEnders' Spoiler: Police Arrest Walford Resident Over The Murder Of Lucy Beale (PICS)

‘EastEnders’ is set to be rocked as a Walford resident is arrested in connection with the murder of Lucy Beale.

While the identity of the suspect is being kept secret until the episode airs on Monday 12 May, it is possible to work out who isn’t arrested.

Ian’s fiancée Denise and Lauren Branning are both visible in the snaps, as is Max Branning who was having an affair with Lucy ahead of her death.

There’s no shortage of suspects in Albert Square, but fans will have to wait until February 2015 to find out who’s guilty of murder.

Producers are even making sure that the cast have no idea who killed the youngster by filming 15 different endings.

Alongside the obvious suspects, Ian’s ex Jane is set to cause suspicions when she’s reluctant to attend the funeral.

Watch all the action unfold on ‘EastEnders’ on Monday 12 May.
