A TEENAGE mum attacked police after "blacking out" at the end of a night serving in a Chinese restaurant, a court heard.

And after admitting police assault and a breach of the peace, Leanne Grogan told of her fear that she had sipped a drink laced with drugs.

Grogan, 19, was arrested after police were called to her house in Scholes Street, Darwen, on Saturday night.

John Wood, prosecuting, told Blackburn magistrates that officers struggled to make any sense of what Leanne was saying. "The police say she was clearly under the influence of some- thing."

He said Leanne lunged at an officer and, during the struggle that followed, she bit an officer on the hand.

Mr Wood said Grogan had no previous convictions and Nigel Holden, defending, said he had been called to the police station at 5am and had been told that Leanne was "incoherent" and unfit to be interviewed.

"I got to see her at about 10am and she was absolutely distraught," said Mr Holden. "Whatever happened to her on Saturday night caused a pattern of behaviour that was totally out of character. She has absolutely no recollection of the events of this night.

Grogan was bound over in the sum of £50 to keep the peace for six months. A fine of £50 for the police assault was written off against the 36 hours spent in custody. She was also ordered to pay £50 compensation.

After the case, she said she had left work at a Chinese restaurant feeling fine but within minutes became deranged and ended up attacking her partner.

"I am convinced someone had drugged a drink that was bought for me in the restaurant," she said.

Grogan's partner, Danny Hartshorn, 22, also speaking after the case, said: "When we got home she fell over and then just went crazy.

DS Julian Platt, of Blackburn CID, said the symptoms described by Grogan were not consistent, in his experience, of date rape drugs.

"That does not mean that she has not been drugged with something else, such as an ecstasy tablet.

"It is too late in this case to follow lines of inquiry, as at this late stage it wouldn't be possible to prove or disprove what she's saying."
