On Wednesday 31 July Miss Margaret Mullen, 38, of Wellington Road, Bridlington denied an allegation of being concerned in the supply of 55.2 grammes of diamorphine at Bridlington on Thursday 7 February.
A second defendant Mr Lewis Hill, 24, of St Aidans Avenue, Sheffield, appeared alongside Miss Mullen and denied two charges of possessing Class A drugs with intent to supply, one in regard to 55.2g of diamorphine and the other concerning 3.43g of crack cocaine.
Mr Hill is said to have committed the offences on the A614 near Driffield on Thursday 7 February.

Presiding magistrate Prudence Blake sent the case to Hull Crown Court for 19 August and granted the pair unconditional bail in the mean time.
