Prior to sale on execution, personal property attached can be sold only “by consent of the debtor and creditor.” R. S., 1930, . Sec. 31, Chap. 95, (and here consent by the debtor is lacking) ; or when “liable to perish, be wasted, greatly reduced in value by keeping, or be kept at great expense” such property, before sale on execution, may be sold by the attaching officer, without consent of the parties. R. S. 1930, Sec. 32, Chap. 95.
The sale of this property finds justification neither in the statute nor other sound principle of law. Such conduct was clearly without authority and improper use of this process.
Furthermore, the attachment was discharged when the officer returned the key to the plaintiff. “When the keeper abandons the possession, the attachment is dissolved.” Wheeler v. Nichols, 32 Me., 233, 240; Gower v. Stevens, 19 Me., 92; Brown v. Howard, 86 Me., 342, 344, 29 A., 1094. The subsequent retention of the money taken was tortious and actionable.

“An officer who attaches property on mesne process and sells it thereon, without the consent of the creditor and owner, or otherwise than by the mode prescribed in the statute, becomes a trespasser ab initio.” Ross v. Philbrick, 39 Me., 29.
“When entry, authority or license is given to any one by the law, and he doth abuse it, he shall be a trespasser ab initio. Or in other words, ‘where the law has given an authority, it is reasonable, that it should make void everything done by an abuse of that authority, and leave the abuser, as if he had done everything without authority.’ Bacon’s Abr. Trespass, B.” Ross v. Philbrick, supra, at page 31; Boston & Maine Railroad v. Small, 85 Me., 462, 465, 27 A., 349.
Improper acts alone, however, in the use of process are not enough to establish liability for abuse of process. Such acts must be accompanied by “the existence of an ulterior motive.” Lambert v. Breton, supra. Was there such here ? The motive may be inferred from the improper acts, as stated in the case last cited. Here there is no necessity to resort to inference, for there is abundance of
