Samir Nasri is being investigated by Spanish anti-doping authorities after his twitter account was hacked on Tuesday night, according to reports in Spain.
A series of bizarre tweets were sent from Nasri's account in response to a post from Drip Doctors, a service he is understood to have used for an intravenous treatment.
While most of the focus was on Nasri's alleged infidelity to his then-girlfriend Anara Atanes, it has now emerged that Nasri could be investigated for anti-doping offences.
Intravenous (IV) infusions have been included on the WADA List of Prohibited Substances and Methods under section M2.
