Bella Kolasinac, the wife of Arsenal’s Sead Kolasinac, was held for bringing a stun gun into the UK.
Anxious Bella Kolasinac bought the weapon for protection following a knife attack on her husband and Gunners team-mate Mesut Ozil last year.
She fled to Germany soon after the incident and obtained a legal permit there to carry an “electro shocker”.
However, it was unknown to her that the powerful device was illegal in Britain — and yesterday The Sun reported she was held by Border Force officers at London Biggin Hill Airport when it was found in her luggage.
She could have been jailed for six months for importing a banned weapon but was let off with a caution after the flight from Frankfurt on Sunday.
However, a spokesman for Kolasinac, 26, said: “It was all a misunderstanding. The electro shocker was still in its packaging and didn’t have any batteries.
“Bella was able to prove she sent emails to the flight operators to make sure she could import it.
“Unfortunately, she was in the air with her phone off when she received an email saying the device was illegal.
