Special judge Arvind Kumar summoned Syms, named as an accused in the supplementary charge sheet, to appear before the court.
A charge sheet was also filed against Syms and two firms — Global Services FZE and Global Traders.
Syms and Michel are both directors of the two firms.
Michel was arrested by the Enforcement Directorate on December 22 last year after his extradition from Dubai.
He is among the three alleged middlemen being probed in the chopper scam by the ED and the Central Bureau of Investigation. The others are Guido Haschke and Carlo Gerosa.
