One night in Venezuela, in South America, the police followed a man home.
He was the man they wanted to arrest for theft.
However, his house stood right on the border between Venezuela and Columbia, with one half in each country!
When the police entered the house, the man ran upstairs to his bedroom, which was in Columbia, and called his lawyer.
The Venezuela police were not allowed to enter Columbia, so they could not go into the bedroom.
They arsed the police in Columbia for help, but the Columbia police could not give it.
The man's crime was not a crime in Columbia.
In the end, the Venezuelan police gave up anf returned to their station empty-handed
