“We have contacted his friends in Delhi and have also spoken to his brother”
The 31-year-old’s is understood to have been on his way to meet new teammates in Kolkata, India when he is said to have fallen off the train in Chhattisgarh.
Officials are understood to have learned Diomande’s identity after his phone was found near his body, which contained identification documents.
Diomande’s body was reportedly in a mutilated state when it was discovered near Baradwar train station.
Police officer Udyan Bear told local media: “It was not clear by which train he was travelling.
“We have contacted his friends in Delhi and have also spoken to his brother and informed him about the incident.”
He is believed to have died on August 9, but details have only now been reported.
The midfielder had only arrived in India one day before after being granted a visa in July.
Police are now searching for Diomande’s bags which appear to have gone missing following his tragic death.
Diomande started his career in his native Ivory Coast with Academie de Sol Beni in 2005.
The following year he moved to Charlton, but failed to make an impact at the club and was loaned out to the now-defunct Belgium club Beerschot AC.
He later returned to the Ivory Coast and spent 12 years with Stella Club d’Adjame.
Diomande represented his country and was part of the side that went to the African Cup of Nations in 2009.
No family members have claimed the body as of yet.
