QUILLIAN, Judge.

The defendant was tried and convicted for the offense of carrying a concealed weapon. While the defendant was being "processed" in the Fulton County Jail, a search was made of his person and a knife was found concealed in his belt.

Prior to the trial the defendant made a motion to suppress on the grounds that his rights under the 4th, 5th, 6th, and 14th Amendments to the United States Constitution were violated by the search. By stipulation the hearing on the motion and the trial were conducted simultaneously. Compare Barnett v. State, 123 Ga. App. 369 ( 180 S.E.2d 921), and cits.

The only issue presented by this appeal is whether the search was conducted pursuant to a valid arrest. The evidence in this regard was to say the least scanty. One of the two individuals who searched the defendant stated: "He was brought in the jail down there on another charge; bound over, I think on a J. P. warrant." This was the only evidence offered in this regard. We note that counsel for the state during argument before the court stated that the defendant "was bound over from Commitment Court."

Under the "fruit of the poisoned tree" doctrine, the search must fall if the original arrest was invalid. Raif v. State, 109 Ga. App. 354, 358 ( 136 S.E.2d 169); Miller v. United States, 357 U.S. 301 ( 78 SC 1190, 2 L.Ed.2d 1332); Wong Sun v. United States, 371 U.S. 471 ( 83 SC 407, 9 S.E.2d 441); Chappell v. United States, 342 F.2d 935, 937; Peterson v. United States, 411 F.2d 1074, 1078. It has been held that the burden is on the state to establish the validity of such original arrest. "Evidence obtained by illegal seizure and search of the defendant's person, by which he is compelled to criminate himself, being inadmissible against a defendant accused of crime, the burden devolves upon the state to show that evidence obtained by search was procured after a legal arrest. Proof that the arrest was legal is not made by the statement of a witness that the arrest was made under a warrant. The conclusion of a witness that a given paper is a warrant under which an arrest may legally be made is not proper proof that such a paper is in fact a warrant by virtue of which a legal arrest has been made, so as to authorize the admission of evidence obtained by means of an arrest under such paper or alleged warrant." Sherman v. State, 2 Ga. App. 148 (1) ( 58 S.E. 393). See Johnson v. State, 111 Ga. App. 298, 305-307 ( 141 S.E.2d 574). See also Peters v. State, 114 Ga. App. 595 ( 152 S.E.2d 647). Here, since there is nothing to show the validity of the original arrest, the evidence of the search was not admissible against the defendant.

The case is reversed with direction that a new trial be granted the defendant.

Judgment reversed. Bell, C. J., and Deen, J., concur.
