8、One possible version:

Yesterday afternoon a robbery happened in a bank in the Park Street.

According to the witnesses' statements, it was five minutes to 5:00 pm, just before the closing time of the bank. And it was raining heavily, with little traffic on the road outside. Suddenly, two young men with masks rushed in and threatened the clerks with guns. Then they put the money in bags, rushed out and drove away with about 20,000"dollars. All the things lasted for only a few minutes.

Fortunately, there was nobody killed or wounded in the robbery. The police are searching for the robbers, hoping whoever gets the connected information calls them up as soon as possible.
