Adds comments from company's spokesperson on affected members and risks in paragraph 1 and last bullet, adds details throughout

April 13 (Reuters) - Gym operator Basic-Fit BFIT.AS has suffered a data breach involving around 1 million members with 200,000 in the Netherlands alone, a company spokesperson said on Monday.

Basic-Fit owns gyms serving over 4.5 million customers across six European countries including France, Germany, and Spain. It also runs a franchise model in six other countries, which uses a separate system and was not affected by the leak.

Breach involves members' bank account details, names, birth dates and contact information

Basic-Fit says the unauthorised access was detected by its system monitoring tools and was stopped within minutes

Members whose data is involved have been informed, Basic-Fit says

The company noted it does not hold members' identification documents and no passwords were accessed, adding that the main risk for affected members would be potential phishing attempts
