The Metropolitan Police said they believe they would have had enough evidence to charge Arnis Zalkans with the murder of 14-year-old school girl Alice Gross.
Speaking at a press conference this morning, police said they collected various evidence against him, including:
- An iPhone cover found concealed inside his garden belonged to Alice
- DNA from a cigarette butt found metres from where Alice's body was found matched Zalkans
