Feared for my life today

I was walking peacefully when I met some friends in the way to a little restaurant. There was a stranger talking to them which I feel fishy. So I stayed with them a little more. There was 2 friends there. One left because her mother called him. So there was in total 3 people including that stranger. He looked at his phone because got bored in the conversation.

The stranger asked to see his mobile phone. He reluctantly gave him. Boom. He now is threatening to throw the mobile away if he will not get some money. At that time I personally observed him closely. I was less that one feet close to him. someone walked on the some iron rods and said he will throw them on the river if they do that again.

When I asked him to politely to return his mobile phone. He told me he is his friend and it is none of my business. So now I was all in to kick his ***,but one thing came in my mind does he have a weapon hidden. So I constant tried to asked him to return it but he was not willing to go. Now the poor boy gave him all him money as a last resort.

But even then he was not returning his stuff. Now I started going aggressive toward him. The goal was to act as a decoy so that the boy could seize the opportunity to get his phone back.

He sat down again telling me he is friend. So I started interviewing him. What was the boy name. He could not answer me. I noticed that he was looking at an empty wine bottle, while talking to me.

I took 2 step back as a safety margin. He broke the wine bottle and started giving death threat. Luckily the boy was able to get his phone while his attention was on me.

We ran around 25 meters only to find cops were filling their car tank. A lady told me that she want to stay anonymous and told me that he know the guy who is a drug addict and just been released.

I asked the cops for help within 2 min at team arrived at the spot searching for him. On the way I explained to him. One undercover police also with them. He knows the places very well.

Arriving at the spot he was gone. I was a bit disappointed. Then I remembered about the iron rods. There were 2 people that was there before the incident happened so I asked them, they have not seen anyone.

I filed a complain. After 15 minutes he was inside the interrogation room and already confessed.

When the time has come to do the identification he was bleeding. I guessed a criminal will always understand the hard way.

I had to wait about one and half hour later. He had some stitches on his eyebrows.

Both of us identified and gave our statement. Before leaving he also returned the stolen money. I met a friend which made the process go faster and was free. It was the first time someone did that to me and ways pretty scary. I guess now I must have some sort of protection now if I am out.

What are your sugesstion???
