Tell me more about it

Dagens Nyheter reports that a group of four men have been arrested, suspected of attempted kidnapping and it’s quite interesting to see how closely tracked they were by the police:
“The Swedish police were tipped off in May by Polish colleagues that four men planned to kidnap a rich businessman in Huddinge”
“When they arrived in Nynäshamn with the ferry from Gdansk the police watched the men and tapped their phones. When they got off the ferry the customs had also received advanced warning. Customs officers searched through their car and found a can of pepper spray, a can of tear gas, a truncheon, and a switchblade. [Presumably these were confiscated.]
The men still decided to proceed preparing the kidnapping.
They went to K-Rauta in Huddinge and bought cable ties, duct tape and two pairs of gloves: The police have pictures of this and copies of the purchases from the cash registers.”
“They were apprehended on May 25th. One of the accused had ’strips of duct tape ready on his trousers’, according to the indictment.”
“…the men had photographs and a map of the businessman’s house and the placement of his safe in the garage.
The business man and his son had on several occasions seen the men move about outside their home.”
“The four men deny having planned any crime.”

Honeybuns comments: “I really want to hear those guys’ explanation.”
