Other viewers expressed their concerns at the excessive references to murder and drug-taking and felt the soap should have included a helpline.
A spokesperson for the BBC responded to the complaints in a statement saying: "Ofcom has received five complaints about last night's episode of EastEnders, on BBC 1. We will assess these complaints before deciding whether to investigate or not."
The live shows saw the hashtag #EELive trending on Twitter as 1 million tweets were posted as the identity of the murderer was finally revealed.
