Paris, Aug 19 (DPA) All three members of a gang that tried to rob a bank in central Paris were in custody Wednesday as police explained the gang used a 17-year-old blonde to open the way.

The teenager clad in chic summery white, charmed her way into the high security area, where she pulled a gun and ordered staff to let in her male accomplices, also teenagers.

The aim had been to raid safes containing clients' valuables - but the bank had no such facility, police said Wednesday.

The youngsters - who apparently failed to do their homework and were unaware of an automatic bank-police link - were then surprised by police who had rushed to the scene.

The three fled through an emergency exit, but two including the girl were caught.
