Evidence required to prove theft if direct evidence is not available

I went to store to purchase some item.Some stranger was standing next to me at store. Next day when I went to the same store that random stranger is blaming me for pickpocketing his mobile saying I was the only one standing next to him. He doesn’t have any direct evidence nor any eyewitness. My question is what all evidence will be required in absence of direct evidence to prove theft beyond reasonable doubt and to get me convicted. Please list all the evidence required by court to prove theft in my case.
