Lorenzo Bocchini was jailed for making crystal meth and distributing it around London in an Uber

Last month, an Italian rugby star, Lorenzo Bocchini, was jailed for cooking batches of crystal meth at his high-tech lab in London's Little Venice and then transporting the drugs around the city using an Uber driver.

Officers said he, his brother Alessandro, 43, and his brother's wife Justine, 36, who were also arrested, used an Uber driver as a courier to deliver 'T-bags' around London.

Other allegations that have been against the company in recent months include that the company's employees 'helped ex-boyfriends stalk their former girlfriends' and are 'forced to work 70-hour weeks to get by'.

A spokesman told The MailOnline: 'This is the first time we have heard any allegation like this and is something we're taking extremely seriously.

'Everyone that partners with Uber must pass the relevant DBS criminal records check which would flag past drugs offences.

'We encourage anyone who has experienced anything of this nature to get in touch with us so we can take the appropriate action.'

He added:

· Lorenzo Bocchini was never an Uber partner and his offences are unrelated to the app

· All drivers using the Uber app in London are licensed by TfL who determine if an applicant is fit to hold a private hire driver license

· We keep all feedback anonymous so anyone can write to us confidentially with any concerns they might have

· We have a law enforcement team that includes ex-Met police officers who liaise with the Met police and other departments to investigate any alleged incidents and support them on other initiatives to avoid potential crimes
