Finding a bag of cash

Finding a bag of cash: it was the day I found a bag of cash, I found it next to the abandoned railway track. I was with my mates looking around after college and we came across a old railway line, as we were looking at the track we saw what looked like a arrow on the track so we took it upon our selves to follow it. at the end of the track we found a black duffle bag which was full to the brim with cash. Every note was a crisp £20 note, they were in sealed bags of £1000 in each bag. me and my mates took the bag to a bush and we emptied the bag on the floor, we counted £10,000. it was a huge shock to all of us so we split it five ways and took off. my first thought would be to pay it in but £2000 in cash would be too risky so I decided to pay £200 in at a time once a month and say it was my monthly wage. After all the money was in my account I went on a shopping spree and spent everything, as I was walking back to the car with all the bags I saw two armed police officers starring at me. I dropped the bags and they ran over and arrested me I just let them take me.
