DOVER, Del. — An attorney for former Wilmington Trust president Robert Harra Jr. has filed an emergency motion seeking postponement of a scheduled October trial of Harra and other former bank executives on fraud charges.

The motion was filed under seal Wednesday, one day after a judge granted a request by Federal Reserve officials to quash subpoenas served by Harra and the other defendants.

The judge will hold a telephone conference on Harra’s motion Tuesday.

Harra, former Wilmington Trust chief financial officer David Gibson, former chief credit officer William North and former controller Kevyn Rakowski are charged with fraud, conspiracy and making false statements to federal regulators.

Prosecutors say they hid the truth about Wilmington Trust’s deteriorating commercial real estate loan portfolio before its collapse and hasty sale to M&T Bank in 2011.
